Solution Overview
Problem
Decorative materials struggle to express artificial picture patterns with a feeling of unevenness that is visible only from a specific observation angle, as existing methods using gloss-adjusting agents result in unevenness that varies with observation angle, making patterns visible from the front but not from an oblique view.
Innovation Solution
A decorative material with a first and second gloss-adjusting layer, where a matting agent with a particle diameter less than 1.0 times the thickness of the lower gloss layer is added, allowing the matting agent to float and reduce the matting effect when observed obliquely, making the picture pattern expressed by gloss difference invisible from that angle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a matting agent is added to a gloss-adjusting layer to create unevenness, then a feeling of three-dimensional unevenness is achieved, but the unevenness becomes visible from all observation angles
Solution Approach 1:
The patent applies different gloss levels to different regions of the decorative material. A first gloss-adjusting layer with lower gloss is applied to specific regions to create the picture pattern, while a second gloss-adjusting layer with higher gloss is applied to other regions. This local differentiation allows the picture pattern to be visible only from specific observation angles while maintaining overall three-dimensional unevenness feeling.
Solution Approach 2:
The patent changes the gloss parameter of the coating layers to control visibility. By adjusting the gloss level of the first gloss-adjusting layer to be lower than the second gloss-adjusting layer, the picture pattern becomes visible only when observed from angles where the lower gloss region reflects light differently. This parameter change enables angular-dependent visibility while preserving the feeling of unevenness.
2Productivity
If two types of coating materials with different glosses are used to express unevenness, then production efficiency is high and flexibility is improved, but the ability to express continuously varying depth unevenness is insufficient
Solution Approach 1:
The patent applies the lower gloss first gloss-adjusting layer partially rather than uniformly across the entire surface. By selectively applying this layer only to specific regions where the picture pattern should appear, the method achieves partial action that maintains high production efficiency while creating the desired visual effect. The selective application allows continuous depth variation to be expressed through gradient gloss transitions.
3Shape
If a gloss-adjusting layer with continuously varying depth is provided to express natural wood vessels, then the feeling of natural unevenness is improved, but the picture pattern expressed by gloss difference remains visible from all angles
Solution Approach 1:
The patent uses a composite structure consisting of multiple gloss-adjusting layers with different gloss levels. The first gloss-adjusting layer with lower gloss contains a matting agent to create the picture pattern, while the second gloss-adjusting layer with higher gloss provides the base unevenness feeling. This composite material approach combines the benefits of both layers to achieve angular-dependent picture pattern visibility while maintaining the feeling of natural unevenness.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution allows for a decorative material that can express a picture pattern visible only from a specific observation angular range, providing clear design expression while maintaining sufficient matting effect and surface strength.
Implementation Method 1
a matting agent is added to, of the first gloss-adjusting layer and the second gloss-adjusting layer, the one with lower gloss, where the matting agent has a particle diameter of less than 1.0 times the thickness of the gloss-adjusting layer with lower gloss

AI summary
In a decorative material, a matting agent is added to, of a first gloss-adjusting layer and a second gloss-adjusting layer, one with lower gloss, where the matting agent has a particle diameter of less than 1.0 times the thickness of the gloss-adjusting layer with lower gloss. The matting agent can be thereby exposed to the surface while floating in the gloss-adjusting layer. Accordingly, a sufficient matting effect can be obtained in front observation, and unevenness imparted to the surface can be reduced; thus, the effect of scattering obliquely entering light is weakened, and the matting effect can be reduced when observed obliquely. Therefore, a picture pattern expressed by the difference in gloss, i.e., a design, can be made invisible when observed obliquely.
