592839 A7 V. Description of Invention (

Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, the hydrophilic treatment agent of the present invention can dry and solidify the water anisotropic molecular compound (A) by heating and drying to form a solid film, or, relative to water-soluble polymer compounds (A) The carboxyl or fluorenyl group contained, and the epoxy-propyl-containing organic compound (C) undergoes a ring-opening addition polymerization to produce a cross-linking reaction, whereby a reaction having a ternary circuit structure is formed in the hydrophilic treatment agent layer. Does not dissolve the film. At the same time as the aforementioned reaction, or after the film is formed, by continuous heating (overbaking), or high-temperature heating and drying, the film's thermal decomposition reaction and thermal oxidative decomposition reaction are carried out, but it can be reduced because of its phenolic compound (B) Such thermal decomposition and thermal oxidative decomposition can also suppress the occurrence of low-molecular substances, which is one of the causes of odor. With the same effect, in the case where the aluminum-containing metal material subjected to the hydrophilic treatment is continuously pressure-processed, the frictional heat generated between the metal mold and the surface of the material suppresses the degradation of the film and prevents the generation of odor. The inhibitory effect on the generation of odor caused by the thermal decomposition reaction and the thermal oxidative decomposition reaction is due to the oxidative resistance of the benzene ageing contained in the component ⑻ skeleton, that is, the thermal oxidative decomposition and thermal decomposition after the formation of insoluble film The phenol compound (B) functionally prevents the radical reaction as an oxidation inhibitor by the radical reaction that accelerates the cleavage of the polymer terminal group. The thermal decomposition of the insoluble film can be used to inhibit the insoluble film. The inherent hydrophilic film performance and hydrophilic sustained performance of hair = great efficacy. Furthermore, the characteristics of the component (B) remaining stably in the insoluble film are described in detail, and it is a matter of course that no odor will be generated under long-term use, and this paper size applies the Chinese National Standard (CNS) A4 specification (2 ] 0 X 297 Gong) 1.
