US 2025/0091086 A1 · COOKING UTENSIL HAVING THERMOCHROMIC LAYER INCLUDING THERMOCHROMIC PIGMENT FOR TEMPERATURE SENSOR USING BISMUTH VANADATE AND METHOD FOR MANUFACTURING THE SAME

Abstract

A cooking utensil having a thermochromic layer including a thermochromic pigment for a temperature sensor, includes: a metal substrate; a primer layer including a fluorine-based resin formed on at least a part of a surface of the metal substrate; a thermochromic layer including a thermochromic pigment formed on at least a part of a surface of the primer layer; and a top coating layer including a curing agent formed on surfaces of the primer layer and the thermochromic layer. The thermochromic pigment is a thermochromic pigment for a temperature sensor using bismuth vanadate.
