Abstract (en)
[origin: CA2341456A1] A coating composition for producing a water washable, protective coating, comprising, by weight, 10-50 % of a mixture of at least two acrylic polymers each having different molecular weights, acid numbers, and glass transition temperatures. The composition includes water and an alkali, in an amount sufficient to maintain the composition at a pH in the range of 7.5 to 9.5 an d is further characterized in that the average molecular weight of the mixture of the at least two acrylic polymers is in the range of approximately 35,000 to 100,000. The average acid number of the mixture is in the range of approximately 65 to 150 and the glass transition temperature of a coating produced by the evaporation of the water from the composition is in the rang e of 0 to 70 ~C.
