Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing photosensitive resin compositions face challenges in achieving improved developing properties, such as reduced developing time and increased sensitivity, due to the low solubility of binder resins with high acid values, which leads to precipitation and inadequate molecular weight during polymerization, and a high ratio of acid group monomers compromising other properties.
Innovation Solution
A silane-based compound represented by Chemical Formula 1 is introduced as an adhesion aid in the photosensitive resin composition, enhancing substrate adhesion strength and improving developing properties, preventing surface stains and defects during subsequent processes, while maintaining excellent quality in photosensitive materials and color filters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the ratio of acid group monomer is increased to improve developing property, then sensitivity is improved, but solubility to solvent decreases causing precipitation during polymerization
Solution Approach 1:
The patent changes the chemical structure parameters of the binder resin by introducing specific functional groups (carboxyl, hydroxyl, or amino groups) at controlled positions within the molecular structure. This allows optimization of the acid value to enhance developing properties while maintaining solubility through proper molecular design, preventing precipitation during polymerization.
Solution Approach 2:
The patent creates a composite binder resin system by combining multiple monomers with different functional groups (carboxyl, hydroxyl, amino) in specific ratios. This composite approach enables simultaneous achievement of high developing property and maintained solubility, as the different functional groups work synergistically to balance adhesion enhancement with molecular weight and solubility control.
2Reliability
If the ratio of acid group monomer is increased to improve developing property, then sensitivity is improved, but other properties are deteriorated due to reduced monomer ratio
Solution Approach 1:
The patent applies local quality by introducing specific functional groups at specific positions within the binder resin molecular structure. Rather than uniformly increasing acid group content throughout, the invention places functional groups strategically to enhance developing properties in specific regions while maintaining overall molecular weight and other desirable properties through balanced molecular design.
Solution Approach 2:
The patent optimizes the parameter of functional group content by introducing carboxyl, hydroxyl, or amino groups in controlled amounts and at controlled positions. This parameter optimization allows enhancement of developing property while preserving other properties such as adhesion, molecular weight, and processability through precise control of monomer composition ratios.
3Reliability
If binder resin with high acid value is used to improve developing property, then sensitivity is improved, but adhesion strength to substrate decreases
Solution Approach 1:
The patent develops a composite binder resin containing multiple functional groups (carboxyl, hydroxyl, amino) that work synergistically to provide both high developing property and strong adhesion. The composite structure allows different functional groups to fulfill different roles: some enhance sensitivity while others maintain adhesion strength through hydrogen bonding and chemical interaction with substrates.
Solution Approach 2:
The patent optimizes the acid value parameter within a specific range (50-150 KOH mg/g) and controls the position and type of functional groups introduced. This parameter control ensures that developing property is enhanced while adhesion strength is maintained through proper balance of functional group content and molecular structure, preventing excessive acidification that would harm adhesion.
