Aqueous emulsion resin compositions

An aqueous emulsion resin composition which comprises:

• (a) a resin composition containing at least one fluoroolefin polymer having crosslinkable group(s) at a terminus and/or a side chain of its molecule and at least one non-fluoroolefin polymer having crosslinkable group(s) at a terminus and/or a side chain of its molecule,
• wherein the fluoroolefin polymer consists of a fluoroolefin and a crosslinkable group-containing fluoroolefin, the crosslinkable-group-containing fluoroolefin being at least one member selected from the group consisting of a compound represented by General formula (I):
• CF2═CF(CF2)a—Y (I)
• [wherein a is an integer from 1 to 10 and Y is SO3M or COOM (with M being H, NH4 or an alkali metal)];
• a compound represented by General formula (II):
• CF2=CF(CF2CFX)b—Y (II)
• [wherein X is F or CF3, b is an integer from 1 to 5 and Y is SO3M or COOM (with M being H, NH4 or an alkali metal)];
• a compound represented by General formula (III):
• CF2=CF—O—(CFX)—Y (III)
• [wherein X is F or CF3, c is an integer from 1 to 10 and Y is SO3M or COOM (with M being H, NH4 or an alkali metal)];
• a compound represented by General formula (IV):
• CF2═CF—O—(CF2CFX—O)d—CF2CF2Y (IV)
• [wherein X is F or CF3, d is an integer from 1 to 10, and Y is SO3M or COOM (with M being H, NH4 or an alkali metal)];

• and
• a compound represented by General formula (VII):
• CH2CFCF2Rf1-(CH2)gX1 (VII)
• [wherein X1 is —CH2OH, —COOR1 (with R1 being H, C1 to C6 alkyl group, Na, K, Li or NH4),
• and Rf1 represents a C1 to C40 alkylene group having atom/atoms substituted with fluorine or —ORf2-(Rf2 represents a C1 to C40 alkylene group having atom/atoms substituted with fluorine or a C3 to C50 ether group having atom/atoms substituted with fluorine);
• g is 0 or an integer from 1 to 6];
• wherein the non-fluoroolefin polymer consists of a non-fluoroolefin monomer or non-fluoroolefin monomers, and
• (b) an emulsifier-modified isocyanate wherein the modifying emulsifier is at least one member selected from the group consisting of polyoxyethylene alkyl ethers, polyoxyethylene monoalkylaryl ethers, polyoxyethylene sorbitan higher fatty acid esters, and polyoxyethylene mono higher fatty acid esters,
• wherein the combination of the crosslinkable group in the fluoroolefin polymer and the crosslinkable group in the non-fluoroolefin polymer is hydroxyl group (fluoroolefin polymer)/hydroxyl group (non-fluoroolefin polymer), carboxyl group (fluoroolefin polymer)/hydroxyl group (non-fluoroolefin polymer), or sulfonic acid group (fluoroolefin polymer)/hydroxyl group (non-fluoroolefin polymer).
