Claims
- 1. A resinous composition for coating use obtained by the reaction of a base resin having both hydroxyl and carboxyl groups which is selected from the group consisting of a polyester resin and an alkyd resin, with an organopolysiloxane resin of the formula: ##EQU7## wherein R is a monovalent organic group attached to Si through C--Si bonding; R' is hydrogen, a C.sub.1 to C.sub.20 alkyl or an aryl group; and n and m each represents a real number of 4 or less, providing that the sum of n and m is 4 or less, and having a number average molecular weight of about 500 to 2000, and with an alkylenimine compound having at least one C.sub.2 to C.sub.3 alkylenimine ring.
- 2. The composition according to claim 1, wherein the organopolysiloxane resin is reacted with the base resin in the weight ratio of 3-80 parts to 97-20 parts.
- 3. The composition according to claim 1, wherein the alkylenimine compound is reacted with the base resin in an amount corresponding to a resinous acid value of 0.1 to 50.
- 4. The composition according to claim 1, wherein 3 to 80 parts of the organopolysiloxane resin is reacted with 97 to 20 parts of the base resin and the alkylenimine compound is then reacted in an amount of 2.times.10.sup.-4 M to 1.times.10.sup.-1 M weight percent of the base resin, wherein ##EQU8##
