Innovation Solution
A solvent-based ink jet ink composition with a moisture absorption rate of 2 (mass %·24 hours) or more at 40° C. and 100% RH, combined with a container featuring an inorganic oxide layer, such as silica, alumina, or titania, to suppress moisture absorption and foreign material generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a metal deposition layer is formed on the surface of the accommodating body to suppress moisture absorption, then moisture absorption is suppressed, but visibility of contents is lowered and cracks easily enter the layer by impact
Solution Approach 1:
The invention changes the material parameter of the surface layer from metal deposition to inorganic oxide coating. This parameter change maintains the moisture barrier function while improving optical transparency and impact resistance, thereby resolving the contradiction between moisture suppression and visibility.
Solution Approach 2:
The accommodating body uses a composite structure combining the base material with an inorganic oxide surface layer. This composite approach integrates the moisture barrier properties of inorganic oxides with the optical and mechanical properties needed for visibility and impact resistance.
2Ease of manufacture
If the ink composition is stored in a conventional accommodating body, then the ink composition can be stored, but moisture infiltrates through the body causing coloring material aggregation and foreign material generation
Solution Approach 1:
The invention modifies the surface property parameter of the accommodating body by applying an inorganic oxide coating with low moisture permeability. This parameter change prevents moisture infiltration while maintaining storage functionality, thereby improving storage stability without sacrificing ease of manufacture.
Solution Approach 2:
The inorganic oxide layer acts as an intermediary barrier between the external environment (moisture) and the ink composition. This intermediate layer blocks moisture infiltration pathways, preventing coloring material aggregation and foreign material generation while allowing the storage system to function normally.
3Adaptability or versatility
If the ink composition has high moisture absorption rate, then the ink composition can be formulated with desired properties, but moisture absorption leads to dispersion stability lowering and foreign material generation
Solution Approach 1:
The invention converts the harmful effect of high moisture absorption tendency into a benefit by using it as a basis for selecting appropriate inorganic oxide coatings. The high moisture absorption rate of the ink formulation allows for desired performance characteristics, while the inorganic oxide barrier prevents actual moisture ingress that would cause instability, effectively turning the potential problem into a design advantage.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The inorganic oxide layer ensures long-term storage stability, prevents foreign material aggregation, maintains visibility, and withstands impacts, while the solvent's high moisture absorption is managed, ensuring effective ink composition integrity.
Implementation Method 1
the container is either of at least a container formed of a member having an inorganic oxide layer... the inorganic oxide layer suppresses the transmission of the moisture
