ABSTRACT:
A high-solid self-adhesive having a solid content of 65 to 75% by weight and composed of an emulsion obtained by emulsion-copolymerizing a vinyl monomer mixture containing acrylate esters as the main ingredient and further at least one hydrophilic monomer of formula (A), (B) or (C). ##STR1## wherein R.sub.1 is H or COOH, R.sub.2 is H or CH.sub.3 and R.sub.3 is H or CH.sub.2 OH.
A process for the production of the high-solid self-adhesive comprising successively adding a pre-emulsion obtained by previously mixing said vinyl monomer mixture, a surfactant mixture of a nonionic surfactant and an anionic surfactant and water, to the reaction system to carry out an emulsion copolymerization in the presence of a catalyst.
