Title:
RECORD MEDIUM FOR INK
Document Type and Number:
Japanese Patent JPS60132785
Kind Code:
A
Abstract:
A recording material, comprising a hydrophobic substrate material with a polymeric coating, has excellent receptivity for inks that do not normally wet hydrophobic substrates. The substrate material is coated with a mixture of polyvinylpyrrolidone and a compatible matrix-forming polymer. The matrix-forming polymer is a material, such as gelatin or polyvinyl alcohol, that is swellable by water and insoluble at room temperature but soluble at elevated temperatures. A transparent base sheet, such as cellulose acetate or polyethylene terephthalate, can be coated with the mixture of polymers to provide a sheet material which can be used in ink jet printers and in pen-type graphics recorders, operating at normal speeds, to record large color-filled areas without puddling, running, orwetness and with high color density and excellent resolution.
