Abstract
Official abstract text for this publication.
To obtain an aqueous coating liquid which affords, by applying it on a plastic substrate and drying it, a coated film excellent in transparency, gas barrier properties, and adhesiveness to the substrate and excellent in homogeneity. An aqueous coating liquid containing a polyvinyl alcohol resin (A), a polyethyleneimine (B), a nonionic surfactant (C), and an aqueous solvent (D).
First claim
Opening claim text (preview).
The invention claimed is: 1. An aqueous coating liquid comprising a polyvinyl alcohol resin (A), a polyethyleneimine (B), a nonionic surfactant (C), and an aqueous solvent (D), wherein the polyvinyl alcohol resin (A) and the polyethyleneimine (B) are present in a weight ratio of 95/5 to 60/40, wherein the nonionic surfactant (C) comprises an ethylene oxide adduct of acetylene glycol and an ethylene oxide-propylene oxide block copolymer. 2. The aqueous coating liquid according to claim 1 , wherein a blending amount of the nonionic surfactant (C) is 0.01 to 5 parts by weight relative to 100 parts by weight of the total amount of the polyvinyl alcohol resin (A) and the polyethyleneimine (B). 3. The aqueous coating liquid according to claim 1 , wherein the polyvinyl alcohol resin (A) is a polyvinyl alcohol resin having a 1,2-diol structural unit represented by the following formula (1): wherein each of R 1 , R 2 , and R 3 independently represents a hydrogen atom or an organic group, X represents a single bond or a linking chain, and each of R 4 , R 5 , and R 6 independently represents a hydrogen atom or an organic group. 4. The aqueous coating liquid according to claim 1 , wherein the aqueous solvent (D) is water. 5. A coated film obtained by applying the aqueous coating liquid according to claim 1 on a substrate surface and drying the aqueous coating liquid.
