“…17,18 Gloss is one of the most important parameters in printing and packaging technology, because gloss affects the print quality by providing a better overall look and greater depth to colors. 35,36 Gloss is a property of a material that is responsible for light reflection from a surface. The methods for measuring gloss depend on the kind of base that is used.…”

Hyperbranched polyglycerol as an additive for water-based printing ink

In this work, the application of hyperbranched polyglycerol as a performance additive for water-based printing inks is demonstrated. The hyperbranched polyglycerol, (BPG), was synthesized through anionic ring-opening polymerization from glycidol using 1-butanol as the starting material. The branched structure of BPG is presented and described. The presence of linear, dendritic and terminal units was confirmed by Moore et al. (Prog Surf Sci 88(3):213-236, 2013) 13 C NMR spectroscopy. BPG was then used as a performance additive in a water-based flexographic printing ink. The impact of a small amount of hyperbranched BPG on the printing ink color was examined by studying the optical density of a full-tone area, the total color difference, DE ab *, and the gloss of the dried ink film. The colorfastness to dry and wet rubbing of overprinted samples was studied. The investigated BPG is shown to be able to improve colorfastness to dry and wet rubbing of prints.

“…In addition to outstanding transparency, liquid repellency, and adherence, our coating can provide wood substrates with desirable glossiness, which is considered as a complex phenomenon resulting from the interaction between light and the coating surface [45]. This is an important property of coatings especially for decorative purposes, and a high-gloss is typically achieved with a smooth coating that does not possess micro-or nano-roughness [46].…”

“…* Light induced curable polymer coating systems have many industrial applications because of their excellent mechanical properties, low energy consumption, reduced VOC emissions, and rapid curing even at room temperature [1]. Acrylic coating systems are among the most broadly used ones in various industrial applications [2].…”

“…Mechanical and other properties of the acrylic coating system depend on the composition, created by acrylic functional monomers and oligomers, photo initiators, and other additives [1,2,6]. Supplementing the polymer system with various additives including biopolymer fillers, one can impart short-term functionality (good destruction in solvent media) for the coating but also change mechanical and other properties.…”

Thin UV curable coating systems is an important research field from the industrial perspective due to the improved environmental profile and wide varieties of characteristics. When used for short-term applications as coatings on natural nail for esthetical and medical reasons, the system may be manipulated to attain various properties, either desired or required by the manufacturer e.g. ensuring both excellent long-term properties (deformability, toughness, and good adhesion) and short-term properties (ability to be destroyed quickly after use). Performance of thin UV curable urethane acrylate composite coatings was investigated depending on the content of the additive. Nitrocellulose (NC), cellulose acetate butyrate (CAB), sucrose benzoate (SB), and silica were evaluated to determine their influence on unreacted composite characteristics (viscosity, suspension pigment stability) and reacted film characteristics (ultimate strength, elongation at break, surface gloss, surface micro hardness, and film adhesion loss). According to the tests performed all additives increase the modulus of elasticity. CAB and NC increase the elongation at break values, and strongly increase the uncured gel viscosity, what makes it inconvenient for application.
