PURPOSE:The titled treating agent, consisting of a reaction product of a long- chain alkylketene dimer with polyvinyl alcohol (PVA) or polyethyleneimine, having improved heat resistance and balance between releasing and bonding and capable of being subjected to releasability imparting treatment without deteriorating release performance even at high temperatures. CONSTITUTION:A treating agent consisting of a reaction product obtained by reacting (A) a long-chain alkylketene dimer, preferably a ketene dimer having >=16C alkyl group, particularly octadecylketene dimer or eicosylketene dimer with (B) polyvinyl alcohol (PVA), preferably having 300-2,700 polymerization degree and >=50% saponification degree or polyethyleneimine, preferably having 300-180,000mol.wt., preferably at 0.3-1.1:1 molar ratio between the components (A) and (B).
