Description of the Related Art Polymers obtained by partially esterifying a polymer of acrylic acid, methacrylic acid and a mixture thereof with an alkyl group having 4 to 8 carbon atoms (hereinafter referred to as "specially modified polyester") have hitherto been available. It is used as the main component of coating materials such as concrete, metal, stone and wood (Japanese Patent Laid-Open No. 2-149456; Nisseki Review, Volume 32, No. 5, 23).
7-242, 1990 etc.). On the other hand, for example, with regard to a hoof protector for ungulates, for horses, for example, one or a mixture of two or more selected from fatty acids having 8 to 22 carbon atoms and fatty acid esters thereof, which is liquid at room temperature, is used. And a hoof oil composition containing a compound represented by a specific chemical formula (JP-A-58-198237); for cattle, it contains a poorly water-soluble metal salt exhibiting alkalinity, a metal salt having an antibacterial effect, and a spreading agent. A cow-hoof protector (Japanese Patent Laid-Open No. 2001-39878) is known. The acrylic polymer is, for example, a nail varnish containing a copolymer of methyl methacrylate and hexyl methacrylate (JP-A-52-139732); a methacrylic acid ester copolymer and a methacrylic acid ester / acrylic acid ester copolymer. It is blended as a film-forming agent as a component of nail polish, such as nail enamel using a polymer as a film-forming agent (JP-A-54-129137).

れ自体に水分調節能はない。Since the above specially modified polyester is not a harmful environmental pollutant but also a material conforming to the ISO standard, development of a new application is required. On the other hand, water is constantly evaporating from the surface of the hoof like the skin, and the water of the hoof is replenished by blood and lymph in the hoof and washing the hoof, and the water balance of the hoof is maintained. Drying of the hoof interferes with the function of the hoof and causes a hoof. In addition, over-humidity of the hoof softens the hoof and causes hoof or rot. Hoof oil is used for the purpose of preventing evaporation of water from the surface of hoof and infiltration of water from the outside, but since it is an oil, it has no ability to control water itself.
