Abstract
This invention relates to a polymeric composition for application onto Reemay and Satin acetate fabric for laser printability with a high level (90% or greater readability of printed characters, washability and enzyme rejection/retardation. The polymeric composition is applied by chemical grafting that involves the use of monomers/prepolymers, catalyst, graft initiator and other ingredients of the composition. The coating thus developed and subsequently applied to Reemay and Satin acetate fabric allows to undergo graft polymerization thereby forming a polymeric film which is chemically bonded to the fabric substrate with strong adhesion. The chemically grafted fabric is highly durable and permanent in terms of distinct legibility of the printed characters on the substrate after 55 launderings or 25 dry cleanings and has excellent level or enzyme rejection/retardation when the coated fabric with laser printed characters are subjected to an enzyme wash process.
