AI Technical Summary

Technical Problem

Traditional inkjet labels lack sufficient durability against UV light and water exposure, requiring special printing systems or additional protective coatings that are cumbersome or expensive, and existing solutions do not adequately withstand outdoor conditions.

Method used

An ink receptive substrate with a unique composition featuring variable particle size silica fillers, partially miscible acrylic polymers, and solid UV absorbers, combined with a nonwoven base layer, to enhance durability, UV resistance, and water resistance.

Benefits of technology

The substrate provides improved UV durability, chemical resistance, and abrasion resistance, allowing for durable outdoor full-color inkjet printing without specialized equipment, maintaining print quality and integrity under harsh conditions.

Abstract

An ink-receiving substrate includes an ink-receiving layer configured to receive at least one inkjet ink. The ink-receiving layer has a plurality of first silica particles and a plurality of second silica particles, wherein the average particle diameter of the first silica particles differs from the average particle diameter of the second silica particles. The ink-receiving layer also has a first acrylic polymer and a second acrylic polymer, wherein the first acrylic polymer and the second acrylic polymer are partially miscible. In one aspect, the ink-receiving substrate includes a base layer configured to support the ink-receiving layer and a high-water-capacity layer configured to reduce water accumulation on the ink-receiving layer.
