DETAILED DESCRIPTION OF THE INVENTION The amine-reactive vinyl polymers used as component (a) are known in the art and can be made by reported procedures.
Preferably, the amine-reactive polymer contains repeating units derived from an activated ester-containing vinyl monomer of the formula: ##STR1## in which the R group is H or Me, the R.
sup.
1 group is hydrogen, alkyl of 1-6 carbon atoms, cycloalkyl of 5-6 carbon atoms, or 2-hydroxyalkyl of 2-6 carbon atoms, and the R.
sup.
2 group is selected from alkyl of 1-6 carbon atoms, cycloalkyl of 5-6 carbon atoms, and 2-hydroxyalkyl of 2-6 carbon atoms.
Suitable vinyl monomers include methyl acrylamidoglycolate methyl ether (MAGME), butyl acrylamidoglycolate butyl ether, ethyl acrylamidoglycolate ethyl ether, butyl acrylamidoglycolate ethyl ether, methyl acrylamidoglycolate ethyl ether and ethyl acrylamidglycolate methyl ether, with MAGME being preferred.
These vinyl monomers are suitably formed by the procedures set forth in EPO Application No.
0138025, which is discussed earlier.
Additionally, attention is invited to a number of illustrative procedures set forth later in this description of the present invention.
The activated ester group-containing polymer may contain repeating units derived from one or more copolymerizable ethylenically unsaturated monomers.
Useful comonomers include, but are not limited to, C.

8, alkyl esters of methacrylic acid, hydroxycontaining monomers such as hydroxyethyl acrylate, hydroxypropyl acrylate, hydroxyethyl methacrylate and hydroxypropyl methacrylate, styrene, alpha-methyl styrene, acrylonitrile, acrylamide, acrylic acid, methacrylic acid, vinyl acetate, t-butylaminoethyl methacrylate, and the like.
The polymer containing activated ester groups may be polymerized, or more preferably copolymerized with these other monomers, according to conventional polymerization techniques.
No special precautions are required
