Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current curable compositions used in manufacturing color filters and solid-state imaging elements face challenges in achieving excellent adhesiveness with supports, leading to issues with film stability and pattern formation during the manufacturing process.
Innovation Solution
A curable composition incorporating a resin with specific constitutional units, including an anionic structure and a quaternary ammonium cationic structure ionically bonded to the anionic structure, along with a radically polymerizable group, which enhances electrostatic interactions and suppresses polymerization, resulting in improved adhesiveness and pattern stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional curable compositions are used, then manufacturing process is simple, but adhesiveness to support is insufficient
Solution Approach 1:
The patent uses a composite resin structure containing both anionic structures (for adhesion to support) and quaternary ammonium cationic structures (for electrostatic interaction with pigment particles). This composite molecular design enables the resin to simultaneously achieve excellent adhesiveness to the support and effective pigment dispersion without requiring multiple separate components.
Solution Approach 2:
The resin molecules are designed with localized functional groups: anionic structures positioned to interact with the support surface for adhesion, and quaternary ammonium cationic structures positioned to interact with pigment particles through electrostatic attraction. This local functional differentiation within the resin structure resolves the contradiction between adhesion and pigment binding.
2Reliability
If resin with high polymerization reactivity is used, then curability is improved, but storage stability deteriorates
Solution Approach 1:
The patent modifies the chemical parameters of the resin by introducing quaternary ammonium cationic structures that create electrostatic stabilization in the composition. This prevents premature polymerization during storage while maintaining the ability to cure properly when exposed to UV light, thus resolving the contradiction between curability and storage stability.
3Manufacturing precision
If conventional resins are used, then composition is simple, but pattern formation quality deteriorates
Solution Approach 1:
The resin is designed as a composite molecular structure containing both anionic and quaternary ammonium cationic groups. This composite structure enables precise pattern formation by ensuring uniform pigment dispersion and strong adhesion to the support, while the molecular design itself remains as a single resin component, minimizing compositional complexity.
4Stability of the object's composition
If resin with strong electrostatic interaction is used, then pigment dispersion is improved, but adhesiveness to support may deteriorate
Solution Approach 1:
The resin molecules are designed with localized functional groups: anionic structures positioned to interact with the support surface for adhesion, and quaternary ammonium cationic structures positioned to interact with pigment particles through electrostatic attraction. This local functional differentiation within the resin structure resolves the contradiction between adhesion and pigment binding.
