Image-Carrying Laminate Barrier Layer Against Ink Migration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ink or dye migration from an image formed on an interlayer film of laminated glass leads to degradation of image definition and resolution in long-term use.
Innovation Solution
An interlayer film for laminated glass, specifically designed to laminated glass, incorporating an image carrier, a resin layer and a transfer prevention member between the image carrier and a transfer prevention member, the transfer prevention member, positioned between the image carrier and the resin layer, and the transfer prevention member, positioned between the image carrier and the resin layer, and the resin layer, preventing materials from transferring therebetween.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If printing is performed on the interlayer film to form an image, then design aesthetics are improved, but ink or dye migration occurs to other resin layers through long-term use, degrading image definition and resolution
Solution Approach 1:
A transfer prevention layer is introduced as an intermediary between the image carrier (printed layer) and the resin layer. This intermediate layer prevents direct contact and material transfer between the printed image and the resin layer, thereby maintaining image definition and resolution while preserving design aesthetics. The transfer prevention layer acts as a barrier that blocks ink or dye migration without interfering with the visual appearance of the image.
2Manufacturing precision
If a transfer prevention layer is added between the image carrier and resin layer, then image definition and resolution are maintained, but the structure becomes more complex
Solution Approach 1:
The transfer prevention layer is implemented as a thin film structure that provides the necessary barrier function without significantly increasing the overall thickness or complexity of the laminate. This thin film approach maintains image definition while minimizing structural complexity. The flexible thin film can be integrated into the existing laminate structure without requiring major design changes.
