Claims
- 1. An adhesion-promoting agent, which comprises a reaction product of (i) an amine compound prepared by reacting an aminoalkylalkoxysilane of the formula: ##STR5## wherein R.sup.1 and R.sup.2 are the same or different and are each an alkyl having 1 to 4 carbon atoms, R.sup.3 is a divalent hydrocarbon group having 1 to 4 carbon atoms, Z is hydrogen atom or an aminoalkyl having 1 to 4 carbon atoms, and m is 0, 1 or 2, and less than equimolar amount of an epoxyalkylalkoxysilene compound of the formula: ##STR6## wherein R.sup.1, R.sup.2, R.sup.3 and m are as defined above, and G is a glycidoxy or epoxycyclohexyl group, with an excess amount of (ii) a .beta.-dicarbonyl compound of the formula:
- R.sup.4 --CO--CH.sub.2 --CO--R.sup.5
- wherein R.sup.4 and R.sup.5 are the same or different and are each an alkyl having 1 to 16 carbon atoms, an aryl having 6 to 12 carbon atoms, or an alkoxy having 1 to 4 carbon atoms.
- 2. The agent according to claim 1, wherein the aminoalkylalkoxysilane is a member selected from the group consisting of N-(.beta.-aminoethyl)-.gamma.-aminopropylmethyldimethoxysilane, N-(.beta.-aminoethyl)-.gamma.-aminopropyltrimethoxysilane, and .gamma.-aminopropyltriethoxysilane, and the .beta.-dicarbonyl compound is a member selected from the group consisting of acetylacetone, ethyl acetoacetate and diethyl malonate.
