Abstract:
A substrate for an abrasive article comprising:a) a backing; andb) a crosslinked treatment coat on said backing, said treatment coat is formed from a curable precursor composition comprising a mixture of:i) from about 30 to about 60 weight percent of an oligomeric aminoplast resin having on average at least one pendant .alpha.,.beta.-unsaturated carbonyl group per oligomeric unit,ii) from about 70 to about 40 weight percent of a thermoplastic polyamide miscible in said aminoplast resin, the weight percents being based on the total resin content, andiii) a sufficient amount of a catalyst for the curable oligomeric aminoplast resin having on average at least one pendant .alpha.,.beta.-unsaturated carbonyl group per oligomeric unit, said catalyst being stable at a temperature of mixing of the components.
