To obtain a coating material for forming a gas barrier layer, which forms a barrier layer having excellent oxygen barrier properties under a high-humidity condition and neither thinning nor causing dissolution/white turbidity/whitening by retort sterilization, a gas barrier resin composition and a gas barrier material such as laminate obtained from the coating material, and to provide a method for producing the coating material or the like by low-temperature heating or short-time heating.
The coating material for forming the gas barrier layer comprises a saccharide (A) and a polymer (C) obtained by polymerizing a monomer (B) composed of N-methylol-based (meth)acrylamide (b1) as an essential component and has ≥3 wt.% of the amount of a part derived from the N-methylol-based (meth)acrylamide (b1) in 100 wt.% of the total of the saccharide (A) and the polymer (C). Preferably, the monomer (B) is (meth)acrylamide or a polymerizable double bond-containing carboxylic acid.
