Abstract:
The present invention provides a water-soluble film having excellent solubility in cold water, high strength, and excellent hard-water resistance. The present invention also provides a method for simply producing such a water-soluble film. One aspect of the present invention relates to a water-soluble film including a polymer containing an anionic group other than a sulfonic acid (salt) group, and a water-soluble resin. The anionic group-containing polymer excludes an acrylic acid homopolymer. Another aspect of the present invention relates to a method for producing a water-soluble film that includes a polymer containing an anionic group other than a sulfonic acid (salt) group, and a water-soluble resin. The method includes mixing a polymer containing an anionic group other than a sulfonic acid (salt) group and a water-soluble resin.

Claim (Index 16):
A method of using a composition comprising a polymer containing an anionic group other than a sulfonic acid (salt) group and a water-soluble resin as a material of a water-soluble film,\n the anionic group-containing polymer excluding an acrylic acid homopolymer, the anionic group-containing polymer further containing, in addition to the anionic group, at least one group selected from the group consisting of sulfonic acid (salt) groups, cationic groups, (poly)alkylene glycol groups, hydrophobic groups, and lactam groups, the cationic groups being derived from a monomer unit derived from a compound represented by the formula (3): wherein R 2  represents a hydrogen atom or a CH 3  group; R b  represents a CH 2  group, a CH 2 CH 2  group, or a direct bond; R c  represents \u2014O\u2014CH 2 \u2014CH(OH)\u2014CH 2 \u2014, \u2014O\u2014CH 2 \u2014CH(CH 2 OH)\u2014, \u2014O-(A 1 O) m \u2014CH 2 \u2014CH(OH)\u2014CH 2 \u2014, or \u2014O-(A 1 O) m \u2014CH 2 \u2014CH(CH 2 OH)\u2014 where A 1 Os are the same as or different from each other and each represent a C2-C18 oxyalkylene group and m is an average number of moles of an oxyalkylene group added represented by A 1 O and is 1 to 300; and R 3 , R 4 , and R 5  are the same as or different from each other and each represent a hydrogen atom or a C1-C30 organic group where one of R 3 , R 4 , and R 5  may be absent,\n the hydrophobic groups being derived from a monomer unit derived from a compound represented by the formula (5): \n wherein R 9  represents a hydrogen atom or a CH 3  group; R d , R e , and R f  are the same as or different from each other and each represent a CH 2  group, a CH 2 CH 2  group, or a direct bond; x 1  represents the number of units represented by (O\u2014CH 2 \u2014CH(OH)) and is 0 or 1; x 2  represents the number of units represented by (O\u2014CH 2 \u2014CH 2 ) and is 0 to 100; x 3  represents the number of units represented by (O\u2014CH 2 \u2014CH(OH)) and is 0 or 1, where x 2  is 1 to 100 and x 3  is 1 when R d , R e , and R f  each represent a direct bond and x 1  is 0; and R 10  represents a hydrophobic group.
