- 4. A reactive composition according to claim 3 wherein (b) is an acrylyl compound and from about 5 to 50% by weight of said acrylyl compound has an equivalent weight of at least about 300 per carbonyl-activated aliphatic double bond and where from about 95 to 50% by weight of said acrylyl compound has an equivalent weight of less than about 300 per carbonylactivated aliphatic double bond.
- 5. A reactive composition according to claim 1 wherein said mixture contains (II.) up to about 50 weight percent of said mixture of said reactive resin.
- 6. A reactive composition according to claim 1 dispersed in a dispersant.
- 7. A reaction product of a mixture of (I.) a copolymer of:
- (a) a hydrazide having the formula R(C(O)--NH--NHR').sub.a where a is a number from 1 to 10, each (O) is a carbonyl oxygen atom, R is selected from the group consisting of --R', --OR', --NR.sub.2 ', --NHNHR', --C(O)NHNHR', and polyvalent organic radicals having molecular weights of from 14 to 15,000, and each R' is a hydrogen atom or a monovalent organic radical having a molecular weight of from 14 to 450 and being free of functions which react with methyl acrylate at 80.degree. C., and
- (b) an unsaturated organic ester having from 1 to 5 aliphatic double bonds activated by a carbonyl group, the average number of said carbonyl-activated double bonds being greater than one, and having a molecular weight of from about 71 to 12,000, and containing (II.) up to about 70 weight percent of said mixture of a reactive resin selected from the group consisting of reactive melamine, urea and phenol-aldehyde resins, their alkylated derivatives and mixtures thereof.
- 8. A reaction product according to claim 7 wherein said mixture contains (II.) up to about 50 weight percent of said mixture of said reactive resin.
- 9. A reaction product according to claim 8 wherein a is no greater than 2, component (b) is selected from the group consisting of acrylates, fumarates, maleates and itaconates, and the average number of said carbonyl-activated double bonds in (b) is at least two.
- 10. A reaction product according to claim 9 wherein said hydrazide has the formula R(C(O)--NH--NH.sub.2).sub.a.
- 11. A reaction product according to claim 10 wherein (b) is an acrylyl compound and from about 5 to 50% by weight of said acrylyl compound has an equivalent weight of at least about 300 per carbonyl-activated aliphatic double bond and where from about 95 to 50% by weight of said acrylyl compound has an equivalent weight of less than about 300 per carbonylactivated aliphatic double bond.
