Abstract
Described herein are heat resistant inks and coating compositions that, when coated on a substrate, impart the feel of paper. The inks and coating compositions do not degrade when exposed to temperatures of 120° C. or greater.
Claims19
A heat resistant ink or coating composition comprising resin, solvent and a heat resistant material comprising nylon particles, characterized in that application of the ink or coating composition on a plastic substrate, imparts the plastic substrate a feel of paper, wherein:
- the nylon particles have a mean particle size of 30 μm to 100 μm;
- a feel of paper is the haptic effect or tactile perception of touching and feeling paper;
- the heat resistant material is not soluble in the resin and solvent;
- the ink or coating composition does not degrade upon exposure to temperatures of 120° C. or greater;
- and
- the feel of paper imparted by the coating is maintained after heat sealing or printing at temperatures greater than 120° C.
3 more elements
A method of coating a substrate with a heat resistant ink or coating comprising:
- applying to a plastic substrate, at a temperature of 120° C. or greater, a heat resistant ink or coating composition comprising resin, solvent and heat resistant nylon particles, wherein the nylon particles have a mean particle size of 30 μm to 100 μm, wherein the ink or coating provides heat resistance at temperatures of 120° C. or greater, and wherein the heat resistant material is not soluble in the resin and solvent;
- and
- drying the coating;
- wherein the ink or coating composition imparts a feel of paper to the substrate, wherein a feel of paper is the haptic effect or tactile perception of touching and feeling paper, and wherein the paper feel imparted by the coating is maintained after heat sealing or printing at temperatures greater than 120° C.
