FIELD: polymer coatings.
SUBSTANCE: invention relates to using powder composition to coat jet printing materials utilized as visual information carriers. Powder composition contains (i) one or several powder silane-containing polyvinyl alcohols based on copolymers of fully or partially hydrolyzed esters having degree of hydrolysis from 75 to 100 mol % and (ii) one or several water re-dispersible polymer powders based on homopolymers or copolymers of one or several monomers selected from group including nonbranched or branched C1-C15-alkylcarboxylic acid vinyl esters, (meth)acrylic acid esters with C1-C15-alcohols, vinylaromatic compounds, olefins, dienes, and vinyl halides.
EFFECT: enabled manufacture of wear-resistant coatings to coat both paper and polymeric substrates, avoided undesired increase in viscosity during composition preparation procedure, and enabled more flexible variation in contents of solids in chalking mass.
