AI Technical Summary
Technical Problem
Conventional cooktop top plates face challenges in achieving both high scratch resistance and adhesion of the heat-resistant resin layer, as increasing pigment content for scratch resistance can lead to delamination and reduced adhesion.
Method used
A cooktop plate design incorporating a heat-resistant resin layer with a specific composition of flake-shaped and needle-shaped crystalline pigments, totaling 85% by mass or more, with a mass ratio of 1.0 to 35.0, enhances scratch resistance and adhesion by optimizing the balance between these components.
Benefits of technology
The design improves both scratch resistance and adhesion of the heat-resistant resin layer, ensuring durability and longevity of the cooktop plate.

Abstract
To provide a top plate for a cooker which can enhance scratch resistance and adhesion of a heat-resistant resin layer.SOLUTION: A top plate for a cooker includes a glass substrate having a cooking surface where a cooking device is mounted and a rear face opposite to the cooking surface, and a heat-resistant resin layer arranged on the rear face of the glass substrate, wherein the heat-resistant resin layer has a layer (X) containing a silicone resin and a pigment, the pigment in the layer (X) contains a scaly pigment (A) having Mohs hardness of 2.5 or more and an acicular crystal pigment (B) having Mohs hardness of 2.5 or more, in the layer (X), the total content of the scaly pigment (A) and the acicular crystal pigment (B) in 100 mass% of the pigment is 85 mass% or more, and in the layer (X), a mass ratio (content of scaly pigment (A) / content of acicular crystal pigment (B)) of the content of the scaly pigment (A) to the content of the acicular crystal pigment (B) is 1.0 or more and 35.0 or less.SELECTED DRAWING: Figure 1
