Abstract: A coating composition comprising as a main component a polymeric resin obtained by solution polymerization of at least one of polymerizable amino acid compounds of either one of the formulas: ##STR1## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are each hydrogen, methyl or ethyl, R.sub.5 is hydrogen or C.sub.1 -C.sub.20 alkyl optionally having --SO--, --COO-- or --O-- therein, R.sub.6 is C.sub.1 -C.sub.12 alkylene optionally substituted with --OH, --SH or --SR.sub.7 (R.sub.7 being C.sub.1 -C.sub.4 alkyl) and/or optionally substituted with C.sub.1 -C.sub.4 alkyl or phenylene optionally substituted with C.sub.1 -C.sub.4 alkyl and A is --COOH or --SO.sub.3 H, and ##STR2## wherein R.sub.8, R.sub.9 and R.sub.10 are each hydrogen or C.sub.1 -C.sub.6 alkyl, R.sub.11 is hydrogen or C.sub.1 -C.sub.20 alkyl optionally having --SO--, --COO-- or --O-- therein, or a group of the formula: ##STR3## (R.sub.8, R.sub.9 and R.sub.10 being each as defined above), R.sub.12 is C.sub.2 -C.sub.

Abstract: A process for preparing a substantially lump free acrylic resin emulsion by emulsion polymerization of one or more acrylic monomers in water in the presence or absence of an emulsifier or a dispersing agent, wherein the polymerization is carried out in the presence a water-insoluble resin which is immiscible with the acrylic resin in the emulsion and has a softening or melting point of 20.degree. C. or higher.
