Duplicating Using Pressure TRIZ Cases
- Revealable Opacifying Layer Using Void-Collapsing Polymer Particles
Irregular polymer particles create an opaque layer that turns transparent by collapsing voids, revealing underlying color without leuco dyes.
- Carbonless Copy Note Pad Coarse Particle Coating Pressure Dispersion
Coarse particle coating layer on note sheet lower surface disperses scribbling pressure, eliminating cardboard divider need while maintaining clear replicas.
- Self-Copy Paper Sheet with Segmented CF and CB Coatings
Segmented CF and CB coatings on a folded paper sheet resolve alignment precision issues while enabling bilingual medical form translation.
- Recording Material With Hollow Polymeric Particles For Opacity Control
Hollow polymeric particles reduce opacity in recording materials, avoiding unstable color precursors while maintaining long-term stability.
- Thermosensitive Recording Layer Forming Liquid Coating Uniformity
A thermosensitive recording layer forming liquid uses an electron-donating compound and a low-solubility electron-accepting compound to form a uniform coating.
- Recording Material Color Former Additive Oil Resistance Stability
Diaminodiphenyl sulfone additives mediate reactions between non-phenolic agents and color formers, resolving oil resistance versus storage stability trade-offs.
- Heat-Sensitive Recording Material with Hollow Pigments and Fatty Acid Amides
A heat-sensitive recording material uses hollow body pigments in a second layer to form images through thermal melting.
- Pressure-Sensitive Recording Material Zinc Salicylate Coating
Web-shaped substrate coated with zinc salicylate color acceptor layer.
