Coating, impregnating and adhesive compositions curable at ambient temperature

A composition, suitable for coating, impregnating, and/or bonding purposes and adapted to be cured under ambient conditions, comprising a liquid vehicle containing:

• (1) A soluble vinyl addition polymer of monoethylenically unsaturated monomers, said polymer containing a plurality of primary or secondary amine groups and/or aldimine or ketimine groups pendant from spaced mers or polymer units in the polymer chain,
• (2) At least one compound having at least two acryloxy groups of the formula
• H.sub.2 C.dbd.C(H)C(O)--O--
• and
• (3) Optionally when component (1) is a polymer containing only primary and/or secondary amine groups, a volatile (C.sub.3 -C.sub.10) ketone or (C.sub.3 -C.sub.10) aldehyde stabilizer which retards the reaction of (1) and (2) under ambient conditions,
• wherein component (1) comprises at least one of:
• (a) An amidation product of a vinyl addition copolymer of a mixture of monoethylenically unsaturated monomers containing a lower alkyl (meth)acrylate with a polyamine having at least two amino groups selected from primary and secondary amino groups and having their nitrogen atoms attached to aliphatic carbon atoms,
• (b) A ketimine or aldimine derivative of (a) obtained by reaction of primary amine groups in (a) with a (C.sub.3 -C.sub.10) ketone or a (C.sub.3 -C.sub.10) aldehyde, and
• (c) A soluble vinyl addition copolymer of a monomer having a general formula H-I, H-II, H-III or E-I, these formulas being as follows:
• ##STR18## where m is an integer having a value of 4 to 5,
• n is an integer having a value of 1 to 2,
• A is a C.sub.2 -C.sub.12 alkylene group,
• R' is a (C.sub.1 -C.sub.12) alkyl or cycloalkyl group,
• R.sup.2 is a (C.sub.1 -C.sub.12) alkyl or cycloalkyl group, and
• R.sup.3 is selected from the group consisting of phenyl, halophenyl, and alkoxyphenyl in which the alkoyl group has one to four carbon atoms, and ##STR19## wherein:
• Q is selected from the group consisting of ##STR20## R is H or it may be methyl in one CHR unit, R.sup.1 is selected from the group consisting of (C.sub.1 -C.sub.12) alkyl and cyclohexyl groups,
• R.sup.2 is selected from the group consisting of (C.sub.1 -C.sub.12) alkyl and cyclohexyl groups,
• R.sup.3 is selected from the group consisting of phenyl halophenyl, (C.sub.1 -C.sub.12) alkyl, cyclohexyl, and (C.sub.1 -C.sub.4) alkoxyphenyl groups,
• A', B, and D are the same or different oxyalkylene groups having the formula ##STR21## R.degree. being individually selected from the group consisting of H and alkyl radicals having 1 to 2 carbon atoms,
• m is an integer having a value of 1 to 2,
• x is an integer having a value of 4 to 5,
• n is an integer having a value of 1 to 200,
• n' is an integer having a value of 1 to 200,
• n" is an integer having a value of 1 to 200, the sum of n-1, n'-1, and n"-1 having a value of 2 to 200,
• the relative amount of (2) to (1), based respectively on acryloxy unsaturation equivalency of (2) and amine (primary and/or secondary) nitrogen equivalency of (1), being such as to provide at least from 0.5 to 3.5 equivalents of (2) for each equivalent of (1).
