Abstract
Abstract Printed decorative paper having a three dimensional pattern comprises base paper 1, a printed design layer 2 formed of a water-based ink as an undercoat on a surface of the base paper, an overlying printed design pattern layer 3 formed of a water-based curable ink containing a repellent in harmony with said pattern in the undercoat, and overlying water-based curable topcoat 4 applied to the entire surface of the base paper in such a way that said topcoat in the areas where said printed design pattern layer 3 is formed is repelled to form concavities 5. This printed decorative paper is environment friendly due to the non-use of organic solvents, is enhanced in durability as a interior decor material and can be produced with high efficiency.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
103 words
A process for producing printed decorative paper having a three dimensional pattern comprising the steps of: forming a printed design layer of a water-based ink as an undercoat on a surface of base paper; overlaying said undercoat with a printed design pattern layer formed of a water-based curable ink containing a repellent corresponding with said pattern in the undercoat; applying a water-based curable topcoat to the entire surface of the base paper; and heating the applied coats with the temperature being varied stepwise such that said topcoat in the areas where said printed design pattern layer is formed is repelled to form concavities.
Claim 2
Dependent Claim
