Electric-Wave-Transmissible Transferring Member Sharp Outline Production
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing electric-wave-transmissible transferring members with metallic luster patterns result in obscure outlines due to insufficient adhesiveness between layers, particularly between the water-soluble paint and the insulating metallic thin film, leading to incomplete removal during the water-washing step.
Innovation Solution
A method involving the formation of a peel layer, a water-soluble pattern layer, an electric-wave-transmissible metallic luster layer, and a protective layer on a base sheet, followed by a heating treatment to enhance adhesiveness, and a water-washing treatment to remove these layers cleanly along the pattern outline, with the option to form an adhesive layer for bonding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If water-soluble paint is painted onto the substrate and then removed by water-washing, then the metallic luster pattern is formed, but the outline becomes obscure due to insufficient adhesiveness between layers
Solution Approach 1:
The invention introduces a peel layer as an intermediary between the water-soluble pattern layer and the base sheet. This peel layer serves as a mediator that enables controlled removal of the water-soluble pattern layer while maintaining the integrity of the metallic luster layer, thereby resolving the adhesion contradiction by providing a dedicated interface for layer separation.
Solution Approach 2:
The invention segments the transferring member into distinct functional layers: a base sheet, a peel layer, and a transfer layer (comprising the insulating metallic thin film and water-insoluble paint). This segmentation allows the water-soluble pattern layer to be removed cleanly along with the peel layer, preventing contamination of the metallic luster pattern and ensuring sharp outlines.
2Illumination intensity
If water-insoluble paint is painted onto the insulating metallic thin film, then the metallic luster is achieved, but the layers fail to remove cleanly together during water-washing
Solution Approach 1:
The invention merges the water-insoluble paint layer and the insulating metallic thin film into a unified transfer layer that is applied simultaneously to the substrate. This merging ensures that both layers remain closely associated during the water-washing process and are removed together along with the peel layer, maintaining their structural integrity and preventing premature separation.
Solution Approach 2:
The peel layer acts as an intermediary that facilitates the cohesive removal of the transfer layer (including both the water-insoluble paint and insulating metallic thin film). By providing a common attachment point, the peel layer ensures that these layers are removed together in a controlled manner, achieving clean pattern formation.

Function Achieved in This Case
This method allows for the production of transferring members that express metallic luster patterns with sharp outlines by ensuring the complete removal of layers along the intended pattern, improving the sharpness and clarity of the decorative surface.
Implementation Method 1
subjecting a workpiece to a heating treatment for heightening adhesiveness between the water-soluble pattern layer, the electric-wave-transmissible metallic luster layer, and the protective layer
Implementation Method 2
subjecting the workpiece to a water-washing treatment, thereby peeling and removing the water-soluble pattern layer

AI summary
A method for producing an electric-wave-transmissible transferring member capable of expressing a metallic luster pattern having a sharp outline. A peel layer (3) is formed on a base sheet (2) throughout the entire surface of the sheet. Next, a water-soluble pattern layer (4) is partially formed thereon. Next, an electric-wave-transmissible metallic luster layer (5) is formed thereon and throughout the entire surface thereof. Next, a protective layer (6) is formed thereon and throughout the entire surface thereof, or is formed thereon and, partially, in the region where the water-soluble pattern layer (4) is not formed. Next, the workpiece is subjected to a heating treatment and then a water-washing treatment to peel and remove the water-soluble pattern layer (4), and the electric-wave-transmissible metallic luster layer (5) and the protective layer (6) formed over the layer (4). Next, an adhesive layer (7) is wholly or partially formed on the workpiece.
