摘要：An aqueous coating composition containing a water-dilutable (water-thinnable)binder mixture of I. from 50 to 88% by weight of a neutralised, water-soluble product ofthe reaction of (A) from 10 to 80% by weight of a polyurethane resin having an acidnumber of from 70 to 160, containing at least one terminal, blocked isocyanate group,and which is free from free hydroxyl groups and fatty acid radicals having more than 12carbon atoms, and having a limiting viscosity index of from 6.5 to 12.0 ml/g, measured inDMF at 20 DEG C, and (B) from 20 to 90% by weight of a polyester resin having an OHnumber of from 50 to 500, an acid number of less than 20, a limiting viscosity index offrom 8.0 to 13.0 ml/g, measured in DMF at 20 DEG C where the reaction product has alimiting viscosity index of from 13.5 to 18.0 ml/g, measured in DMF at 20 DEG C, II. from 10to 40% by weight of one or more non-water-dilutable, blocked polyisocyanates, and III.from 2 to 30% by weight of at least one amino resin as further crosslinking agent.
