Abstract
Disclosed are improved styrene-butadiene (SBR) core-alkyl acrylate/methacrylate shell-polymer compositions and an improved process for applying patterns to textiles by screen printing employing these polymer compositions as binders. The process for preparing the improved polymers is also set forth. The core comprises an SBR copolymer which contains an antioxidant and is at least partially encased by an integral shell of a copolymer of an alkyl acrylate or methacrylate which is formed by copolymerization with an ultraviolet light stabilizer. When used as binders for screen printing, these compositions produce textiles which exhibit a desirable combination of crock fastness, cyclic aging and hand properties.
