| abstract |
Aqueous compositions, suitable for printing, are described which have a high volume solids content. They comprise primary polymer particles and a secondary polymer which provides temporary adherence of the particles to a substrate before the primary polymer is fused by a heating step, in a printing process, in order to cause permanent adherence. There are advantages over the use of organic solvent-based and other aqueous compositions, such as easier cleaning, low toxicity/fire hazard and lower cost. |
