Application of ketone resin in black ink and its testing method

This study uses a ketone resin that is excellent in nature, an appropriate mixture of solvents, dyes, and a new type of surfactant. The rheological measurement is performed with the aid of a Sidarhak RV-100 rheometer, making the results ideal. The rheological property index and viscosity-temperature coefficient keep the writing performance of the ink under different temperature conditions. After testing, the aging resistance, writing lubricity, oil splashing, and sealing are all higher than the similar products in the same category, and can be comparable to foreign advanced products. . After verification, this product has reached the ministerial level one ink index and is a new ink system.
