Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing glitter pigments fail to achieve desired reflected light effects due to the lack of effective integration of pigment particles with optical interference films.
Innovation Solution
A glitter pigment comprising a flaky substrate with an optical interference film and composite particles consisting of pigment and oxide particles attached to the film, enhancing color expression and preventing detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a pigment particle is attached onto an optical interference film, then color tone adjustment is achieved, but the pigment particle detaches from the film
Solution Approach 1:
An oxide particle serves as an intermediary between the pigment particle and the optical interference film. The oxide particle is attached to the film first, creating a stable base, and then the pigment particle is attached to the oxide particle. This mediator structure prevents direct detachment of the pigment from the film while maintaining color tone control.
Solution Approach 2:
The invention creates a composite structure consisting of three components: the optical interference film, the oxide particle, and the pigment particle. This composite material approach combines the advantages of each component - the film provides optical interference effects, the oxide particle provides stable attachment, and the pigment particle provides color tone control.
2Illumination intensity
If only an optical interference film is used, then pearlescent luster is achieved, but color vividness is insufficient
Solution Approach 1:
The invention merges two separate functional components: the optical interference film (providing pearlescent luster) and the pigment particle (providing color vividness). By combining these components into a single integrated glitter pigment structure, both the pearlescent luster and color vividness are achieved simultaneously without compromising either property.
