Decorative Laminate Textured Matte Surface Fingerprint Masking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High pressure decorative laminates are susceptible to fingerprint buildup on their surfaces, which existing chemically modified surfaces have not effectively addressed.
Innovation Solution
A decorative laminate lay-up with a textured matte surface is created using a textured release sheet coated with an electron beam radiation curable epoxy acrylic material, where the coating is partially crosslinked with UV radiation and fully crosslinked with electron beam irradiation, resulting in a matte finish that prevents fingerprint visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a smooth glossy surface is used for decorative laminate, then the surface appearance is attractive and clean, but fingerprints are clearly visible and build up during regular use
Solution Approach 1:
The patent applies a textured matte coating specifically to the surface layer of the decorative laminate, creating a localized change in surface properties. This textured layer diffuses light at the micro-level, masking fingerprints while maintaining the overall aesthetic appearance of the laminate. The core laminate structure remains unchanged, preserving its structural integrity and glossy appearance beneath the textured surface layer.
Solution Approach 2:
The patent changes the surface parameters by applying a textured matte coating that alters light reflection characteristics. The coating creates a non-glossy surface with specific grain patterns that scatter light, thereby hiding fingerprints. This parameter change affects surface roughness, light reflectivity, and fingerprint visibility without compromising the underlying laminate structure.
2Object-affected harmful factors
If a textured surface is applied to reduce fingerprint visibility, then fingerprint proofing is improved, but the surface scratch resistance may be compromised
Solution Approach 1:
The patent uses a composite structure consisting of the base decorative laminate and an overlay with textured matte coating. The textured overlay is specifically engineered to provide fingerprint resistance while the underlying laminate provides structural strength and scratch resistance. This composite approach allows each layer to fulfill its specific function without compromising the other.
Solution Approach 2:
The textured matte coating incorporates grain patterns with curved and irregular surface profiles that scatter light effectively. These micro-curves and grains create a surface topology that masks fingerprints through light diffusion while the overall coating structure maintains sufficient hardness and adhesion to provide scratch resistance.

AI summary
A decorative laminate lay-up includes a decorative laminate sheet assembly composed of an exterior overlay paper layer, a decorative layer, and a core layer. The decorative laminate lay-up includes a texture imparting member in the form of a textured release sheet including a top side and a bottom side. The textured release sheet includes a textured matte surface formed on the bottom side thereof and ultimately applied the textured matte surface to a resulting decorative laminate.
