摘要：PURPOSE:To provide a paint compsn. having internal catalytic function, by incorporating an acid having a specified strength in a resin having a functional group reactive with a crosslinking agent in a state capable of exhibiting a resin acid value within a specified range, and combining said resin with a crosslinking agent. CONSTITUTION:Wa pts.wt. (on a solid basis) resin having both a functional group reactive with carboxyl group and one reactive with a crosslinking agent, such as aminoplast, and Wb pts.wt. polybasic acid exhibiting a half-equivalent point potential of -30mV or above as measured by non-aqueous potentiometric titration in a state capable of exhibiting resin acid value, are subjected to an esterification reaction until the resin acid value reaches N+M, whereby the desired resin compsn. can ben obtd. The above-mentioned Wb is a value calculated bad on the formula, wherein E is gram equivalent of polybasic acid; P is conversion % of polybasic acid to be reacted with resin; N is a resin acid value due to a polybasic acid of the final resin and is 2-50, M is initial resin acid value of resin). Said resin and a crosslinking agent are combined together in a weight ratio (on a solid basis) of 95/5-45/55 to obtain a路由器接路由器怎么设置
