Methacrylic Acid → 2-Propenoic acid, butyl ester, polymer with 2-ethylhexyl 2-propenoate

Participants

Reaction Steps

A total of 20 parts by weight (60 g) of methacrylic acid, 10 parts by weight (30 g) of methyl methacrylate, 55 parts by weight (165 g) of butyl methacrylate, and 15 parts by weight (45 g) of hydroxyethyl methacrylate were dissolved in 300 g of butyl lactate, 0.75 parts by weight (2.25 g) of azobisisobutylnitrile was added under a nitrogen atmosphere, and an acrylic copolymer resin was obtained by reaction for 5 h at 70° C. The acrylic copolymer resin thus obtained was diluted with propylene glycol monomethyl ether acetate to a resin concentration of 10% and a diluted solution of acrylic copolymer resin was obtained. A total of 19.0 g of a pigment and 0.9 g of a dispersant were added to 80.1 g of the diluted solution, the components were kneaded with a three-roll system, and colored varnishes of red, green, and blue colors were obtained. Propylene glycol monomethyl ether acetate was added to the colored varnishes to obtain a pigment concentration of 12-15% and a viscosity of 15 cps, and R, G, B colored inks were obtained.
