Decorative Material Gloss-Adjusting Layer Matting Agent Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Decorative materials that use a gloss-adjusting layer with a matting agent struggle to achieve both high scratch resistance and designability, particularly for applications like top boards and shelf boards, due to the matting agent's effect on surface unevenness and light scattering.
Innovation Solution
The average particle diameter of the matting agent in the gloss-adjusting layer is set within the range of 6.0 µm to 15.0 µm, and the thickness of the gloss-adjusting layer is maintained between 1 µm and 18 µm, with a ratio of 1.2 times or less than the particle diameter, to enhance scratch resistance and designability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a matting agent is added to the gloss-adjusting layer to create surface unevenness for three-dimensional expression, then designability is improved, but scratch resistance deteriorates
Solution Approach 1:
The patent applies parameter changes by precisely controlling the average particle diameter of the matting agent within 6.0-15.0 µm and the layer thickness within 1-18 µm. This optimization allows the gloss-adjusting layer to provide sufficient surface unevenness for three-dimensional design expression while maintaining adequate scratch resistance for practical applications.
Solution Approach 2:
The patent uses a composite structure consisting of a substrate, a design pattern layer, and a gloss-adjusting layer containing matting agents. This composite material system allows the combination of different functional properties: the substrate provides structural support, the design pattern layer provides visual design, and the gloss-adjusting layer with optimized matting agents provides both three-dimensional expression and acceptable scratch resistance.
2Adaptability or versatility
If the gloss-adjusting layer thickness is increased to enhance three-dimensional unevenness expression, then designability is improved, but the amount of resin used increases
Solution Approach 1:
The patent optimizes the thickness parameter of the gloss-adjusting layer to be within 1-18 µm, with the thickness being 1.2 times or less than the particle diameter of the matting agent. This parameter optimization achieves effective three-dimensional unevenness expression using minimal resin quantity, reducing material consumption while maintaining design quality.
3Adaptability or versatility
If the average particle diameter of the matting agent is increased to enhance surface unevenness, then designability is improved, but scratch resistance deteriorates
Solution Approach 1:
The patent precisely controls the average particle diameter parameter of the matting agent within 6.0-15.0 µm. This optimized particle size range creates sufficient surface unevenness for three-dimensional design expression while preventing excessive protrusion that would compromise scratch resistance, thus resolving the contradiction between designability and durability.

AI summary
Provided is a decorative material having excellent designability and scratch resistance. Of first and second gloss-adjusting layers (5, 6), one with lower gloss contains a matting agent having an average particle diameter of 6.0 µm or more and 15.0 µm or less. That is, the average particle diameter of the matting agent in the gloss-adjusting layer with lower gloss, i.e., the gloss-adjusting layer whose scratch resistance is likely to be low, is set within an optimal range in which the gloss-adjusting layer has excellent scratch resistance and designability. In this manner, the scratch resistance and designability of the entire decorative material (1) can be improved. Thus, a decorative material (1) having excellent scratch resistance and designability can be provided.
