Abstract

Provided are: a novel metal alkoxide exhibiting excellent hydrolysis resistance, and an aqueous resin crosslinking composition and an aqueous resin composition which use the same. The metal alkoxide being used is represented by formula (1-1), (1-2) or (1-3), and has a mass average molecular weight of 800-8,500. The formula (1-1) is Ti(OA)4, the formula (1-2) is Zr(OA)4, and the formula (1-3) is Al(OA)3. Each A independently represents a residue obtained by removing a hydroxyl group from a polyalkylene glycol monohydrocarbyl ether represented by formula (1a) that is R11(OCHR12CH2)nOH. In formula (1a), R11 represents a C1-4 alkyl group or phenyl group, R12 represents a hydrogen atom or a C1-4 alkyl group, and n is an integer of 4-45.

Description

technical field [0001] The invention relates to a novel metal alkoxide, a crosslinking agent composition for water-based resin and a water-based resin composition using the metal alkoxide. Background technique [0002] Water-soluble or water-dispersible water-based resins are excellent in handling properties in terms of environment and safety, and therefore are used in various applications such as paints, inks, fiber treating agents, adhesives, and coating agents. In order to impart water solubility or water dispersibility to the resin itself, hydrophilic groups such as hydroxyl groups and carboxyl groups are introduced into the water-based resins. Therefore, water-based resins tend to deteriorate in water resistance and durability compared with oil-based resins. [0003] Therefore, in order to improve various physical properties such as water resistance, durability, and strength of the water-based resin, a crosslinking agent is added to the water-based resin. [0004] As ...
