Problems solved by technology

However, in these silyl group-containing PVAs, setting the upper limit of the above-mentioned product (P×S) to 370 does not eliminate the need to increase the content of monomer units having silyl groups to improve the performance of silyl group-containing PVA. Trade-off relationship between characteristics and improvement of water solubility, etc.
That is, as described in paragraph 0009 of the above-mentioned Japanese Patent Laid-Open No. 2004-43644, when the product (P×S) is 370 or more, there is an inconvenience in the following operations, that is, if the PVA containing a silyl group is prepared, When adding alkali or acid to the aqueous solution, it cannot be dissolved
In other words, the above-mentioned silyl group-containing PVA cannot be said to sufficiently solve the above-mentioned inconvenience.
[0005] In addition, for films obtained from compositions containing PVA, higher water resistance (including boiling water resistance) or anti-blocking properties may be required in accordance with various usage forms, etc.

[0212] [Synthesis Example 1] Preparation of PVA1

[0213] In a 6L detachable flask equipped with a stirrer, a reflux cooling pipe, a nitrogen introduction pipe, a comonomer dropping port, and an initiator adding port, 1,500 g of vinyl acetate, 500 g of methanol, and 1.87 g of methanol having the above formula In the MAmPTMS of the monomer (monomer A) of the group represented by (1), nitrogen substitution was performed in the system for 30 minutes while nitrogen bubbling was performed. In addition, as a delay solution (delay solution), MAmPTMS was dissolved in methanol to prepare a comonomer solution with a concentration of 8%, and nitrogen replacement was performed by bubbling with nitrogen gas. The temperature rise of the reactor was started, and when the internal temperature reached 60°C, 0.8 g of 2,2'-azobisisobutyronitrile (AIBN) was added to start polymerization. The delayed solution was added dropwise, and the polymerization was carried out at 60° C. for 2.7 hours while...

[0231] (composition and film preparation)

[0232] A 4% aqueous solution of PVA1 prepared was added to a 10% aqueous solution of titanium lactate (Ti compound: TC-310 manufactured by Matsumoto Pharmaceutical Co., Ltd.), so that the titanium lactate solid content relative to 100 mass parts of PVA solid content was 10 mass parts, and obtained Composition of Example 1. This composition was cast at 20° C. to obtain a film with a thickness of 40 μm.

[0233] (Composition and Preparation of Thermosensitive Recording Material)

[0234] 90 g of aluminum hydroxide powder (manufactured by Showa Denko Co., Ltd., Higilite H42) was poured into 210 g of distilled water, and stirred by hand. Then, it was stirred at a rotation speed of 13,500 rpm for 5 minutes using a homomixer (manufactured by IKA-Labortechnik, T-25-SI type) to prepare a dispersion liquid of aluminum hydroxide (aluminum hydroxide concentration: 30%). In addition, the PVA1 obtained above was dissolved in water to prepare a...
