Abstract
A transparency comprised of a supporting substrate, thereover a first coating layer comprised of an ink absorbing layer and a biocide; and a second ink spreading coating layer comprised of a hydrophilic vinyl binder, a dye mordant, a filler, an optional lightfastness inducing agent, and an ink spot size increasing agent selected from the group consisting of hydroxy acids, amino acids and polycarboxyl compounds; and wherein the first coating is in contact with the substrate and is situated between the substrate and the second ink coating, and which transparency possesses a haze value of from about 0.5 to about 10 and a lightfastness value of from about 95 to about 98.
Claims31
A transparency comprised of a supporting substrate, thereover a first coating layer comprised of at least one ink absorbing polymer layer and a biocide;
- and a second ink coating layer comprised of a hydrophilic vinyl binder, a waterfastness dye mordant, a filler, an optional lightfastness inducing agent, an optional biocide, and an ink spot size increasing agent selected from the group consisting of hydroxy acids, amino acids and polycarboxyl acids;
- and wherein the first coating is in contact with the substrate and is situated between the substrate and the second ink coating.
A transparency comprised of a supporting substrate, thereover and thereunder a first coating layer comprised of an ink absorbent binder two polymer mixture with excellent adherence to the substrate, and wherein the first polymer of the mixture is present in amounts of from about 24 parts by weight to about 75 parts by weight, and the second polymer of the mixture is present in amounts of from about 75 parts by weight to about 24 parts by weight, and a biocide is present in an amount of about 1 part by weight;
- and a second polyvinyl alcohol ink receiving layer containing hydroxy acids, amino acids, or polycarboxylic compounds, and waterfastness dye mordant of cationic quaternary compounds, said waterfastness mordant being present in amounts of from about 25 parts by weight to about 1.9 parts by weight, and a filler present in amounts of from about 5 parts by weight to about 0.1 part by weight, and wherein the first coating is in contact with the substrate and is situated between the substrate and said second ink receiving layer, and which transparency possesses a haze value of from about 0.5 to about 6 and a lightfastness value of about 95.
A transparency comprised of a polyethylene terephthalate substrate, thereover and thereunder a first coating layer comprised of a blend of super absorbent acrylic acid-acrylamide copolymer and hydroxyethyl methyl cellulose, and a biocide of 2-hydroxypropylmethane thiosulfonate, and a second coating layer comprised of a blend of polyvinyl alcohol, 3,5-dihydroxy benzoic acid, a dye mordant of polymethyl acrylate trimethyl ammonium chloride, and a filler is colloidal silica.
