Abstract
Paper is coated with a composition comprising inorganic pigment having a good water resistance, at least one water soluble binder and at least one compound capable of reacting with starch, the water soluble binder being a low viscosity reaction product of starch with cyanamide and the compound capable of reacting with starch being a mono- or polyaldehyde or a resin precondensate containing methylol groups. The term "low viscosity" is defined as meaning a viscosity of the starch reaction product after complete gelatinisation in distilled water not exceeding 200 cps. when measured at a solids content of 15% at 30 C. with a Brookfield Viscosimeter using Spindle 2 at 60 r.p.m. In the examples 1) a coating composition consisting of china clay, tetrasodium pyrophosphate, cyanamide starch and urea formaldehyde resin is applied by air knife coating to paper followed by calendering 2) and 3) a melamine formaldehyde resin is used as the compound capable of reacting with starch 4) box board is coated with a coating composition consisting of china clay, calcium carbonate, casein, cyanamide starch, a latex of styrene-butadiene and melamine resin 5) a composition comprising china clay, tetrasodium pyrophosphate, and acid modified cyanamide starch, glyoxal, styrene-butadiene latex was applied with a coating rod to paper.
