“…The content ratio of IBSS and MMA units could be deduced from the ratio of the integral area of 3.79-3.86 ppm (-SO 3 CH 2 -) and that of 3.56 ppm (-COOCH ). With the content ratio of IBSS and MMA and the acid value of MAA (12.2 wt.%), the composition of the TP1 could be determined [10], i.e. IBSS:MMA:MAA (mol) = 51.5 %:24.5 %:24 %.…”

Three copolymers containing isobutyl p-styrenesulfonate (IBSS) and carboxyl units, i.e. methyl methacrylate (MMA) and methacrylic acid (MAA), were synthesized and their chemical structures and thermal behaviors were investigated by using TGA, DSC, FTIR and other methods. Films were prepared by using the synthesized copolymers in combination with a bisvinyl ether compound, i.e. 2,2-bis(4-(2-(vinyloxy)ethoxy)phenyl)propane (BVPP), to applied onto an aluminum plate. Crosslinking and de-crosslinking reactions would readily take place when the polymer films were baking treated at 100 oC and 200 oC for a short period of time, respectively. Along with the chemical structural changes during thermal treatments, an affinity change was achieved from being insoluble to completely soluble in neutral water. A positive-working and neutral water-developable imaging material was proposed and preliminary studies on the imaging properties were conducted.

“…The mechanism of negative working is shown in Scheme 1. Several groups have reported various water-developable materials and their applications, such as base-amplifying copolymers and positive-working photoresist, flexographic printing plates consisting of a photosensitive matrix and the diffusion of unreacted component and positive working heat-sensitive imaging composition [5][6][7][8][9][10][11][12]. In our previous work [13], we have also studied a water developable thermo-sensitive latex film.…”

This paper was focused on the synthesis and properties of a watersoluble resin having tertiary amine oxide side substituents. First, 3-(dimethylamino)propanoic acid was synthesized through the addition reaction of dimethylamine with methyl acrylate, followed by hydrolysis of the adduct. Then, 3-(dimethylamino)propanoic acid was oxidized with hydrogen peroxide to obtain 3-(dimethylamino)propanoic acid oxide. Finally, epoxy phenolic was reacted with 3-(dimethylamino)propanoic acid oxide to get the end product. Thermal behaviors and thermo-induced solubility change of the prepared resin were investigated. It was found that the tertiary amine oxide resin was still water soluble even after heating at 120°C for 1 h. However, it readily became completely water insoluble after heating at 170°C for a short period of time. Thin films were prepared with the aqueous solution of the tertiary amine oxide resin and an infrared (IR) dye with maximum absorption at 830 nm. The films could absorb 830 nm IR imaging radiation and give negative image after developing with neutral water. The water-soluble thermosensitive resin might be used in chemical-free thermal laser imaging applications.

“…To a great extent, these problems are the inherent problems of thermal CTP's imaging mechanismthermally induced variations of the molecular aggregates and intermolecular physical interactions which are not great enough to provide sufficient solubility differential between the exposed and unexposed areas. Based on this background, a lot of work still needs to be done to overcome these shortcomings [4][5][6].…”

“…In our previous work, we found that divinyl ethers were very reactive with carboxylic acid at suitable temperatures (typically 80-120 °C) and could be an effective cross-linker for polymers with pendant carboxyl groups [6]. The bridging mechanism is the formation of acetal ester bond between the polymer chains through the reaction of carboxyl group with the divinyl ether group.…”

The performances of CTP plate depend heavily on polymer binder and those capable of producing large image contrast by exposure are keys to quality plate. This research proposed a polymer resin containing hydrophilic spices in the side chain which could be sheltered by the thermal induced crosslinking reaction during plate manufacturing process and released upon imaging exposure. The resin was prepared through esterification reaction of maleic anhydride with phenolic resin, and its chemical structure was characterized by IR spectrum. Plate coatings were formulated with the modified polymer as binder resin, 2,2-bis(4- (2-(vinyloxy)ethoxy)phenyl)propane as the crosslinking agent, a near infrared absorbing dye and crystal violet as the tracing agent. Solubility of the exposed and unexposed coatings in diluted aqueous alkaline was investigated in situ using a home-made dissolving rate tester. It was found that polymer containing 4-6% mole carboxyl groups led to high image contrast and this contribution came directly from the cross-linking and decrosslinking reactions. Preliminary test indicated that this polymer coating generated positive image of high contrast after exposure and could be used as CTP plate coating for thermal laser imaging.
