摘要:
An optical information memory medium comprising a substrate, an improved underlying layer formed on the substrate surface, and a recording layer formed on the underlying layer and mainly consisting of an organic pigment is disclosed. In this optical information memory medium, the underlying layer is formed by causing a compound containing a hydroxyl or carboxyl group selected from the group consisting of a radical polymerizable monomer containing a hydroxyl or carboxyl group, a copolymer obtained from a monomer containing a hydroxyl or carboxyl group, and a polymer compound containing a hydroxyl or carboxyl group to react with a hydrolyzed condensate which is derived from an alkoxide or an aryloxide of a metal selected from the group consisting of Al, Ti, Zr, In, Zn, Mg, Ni, and Cu or from a chelate compound mainly consisting of the metal. An underlying layer formed of a hydrolyzed condensate which is derived from the alkoxide or the aryloxide of a metal selected from the group consisting of Al, Ti, Zr, In, Zn, Mg, Ni, and Cu is also disclosed.

It is intended to provide a tampon wherein a string-shaped member is bonded to a cylindrical absorbent in the state of not being exposed on the absorbent surface. A tampon comprising an absorbent (2), which is obtained by molding a sheet member into a cylindrical shape, and a string-shaped member (4) which is bonded to the absorbent (2) and extends from one end of the absorbent (2). The string-shaped member (4) has a first string part which is bonded along the first direction of one face of the sheet member constituting the absorbent (2) and a second string part which extends from the sheet member. A first folding part is formed in one side of the second direction that is perpendicular to the first direction of the first string member, while a second folding part is formed in the other side of the second direction. Owing to this constitution, the absorbent (2) is deformed by bending respectively from the first folding part and the second folding part and thus molded into a cylindrical shape from which the first string part is not exposed.

An individual package of sanitary tampon that can be easily opened and can avoid any unintended seal breakage while being carried. The individual package of tampon comprises a vertically long, flat bag body made of a sheet-shaped member and a tampon with applicator individually enclosed in the bag body. The individual package further comprises a seal breaking part with one or more cut portions provided continuously or intermittently along a given direction of the sheet-shaped member and a buffer structure part provided on one side or both sides of the seal breaking part in the seal breaking direction. The buffer structure part has a slack portion formed by slacking the sheet-shaped member.

An anti-glare film is provided and includes micro concave/convex portions on a surface. An average interval between the micro concave and convex portions is equal to 300 μm or less. A differentiation with respect to angle d{Log(I(α))}/dα of a logarithm intensity of reflection Log(I(α)) in a direction of a deviation angle α from a direction of specular reflection has an extreme value. A differentiation d{Log(P(β)}/dβ of a histogram P(β) to an inclination angle β of the micro concave/convex portions has an extreme value. In the anti-glare film 1, a value C(2.0) of transmitted image clarity measured by using an optical comb of a comb width of 2 mm in accordance with JIS-K7105 is equal to 30% or more, and a ratio C(0.125)/C(2.0) of the value C(2.0) measured by using the optical comb of the comb width of 2 mm and a value C(0.125) measured by using an optical comb having a comb width of 0.125 mm is equal to 0.1 or more.

An applicator for a tampon comprises an outer cylinder (2) containing an absorber (4) therein and provided with a petal-like components (8) for pushing out the absorber (4) on one side thereof and with a grip cylinder (7) on the other side thereof, and an inner tube (3) which is inserted into the grip cylinder (7) and can push out the absorber (4) to the outside from the petal-like components (8) by moving into the outer cylinder (2). A plurality of rows of annular protrusions (11, 12, 13, 14) are formed in the whole area of the grip cylinder (7) in the circumferential direction, such that the height from the outer circumferential surface of the grip cylinder (7) decreases gradually toward the side of the inner tube (3) being inserted into the grip cylinder (7).
摘要:
An anti-glare film has a plurality of diffuser elements, and has specified optical properties. The ratio of I(α+1)/I(α) is more than 0.1 to 0.6, where I(α) is an intensity of a light reflected toward an arbitrary angle α of 10° or less from a specular reflection direction of an incident light upon the surface at an angle of 5° to 30° from the surface normal, and I(α+1) is an intensity of a reflected light deviated from the arbitrary angle α by 1° in a wide-angle direction. The gain of a light reflected in the direction at 20° or more from the specular reflection direction of the incident light is 0.02 or less, in which the gain is obtained by normalizing a reflected light intensity using a specular reflection intensity of a standard diffuse plate as 1. The diffuser elements have an average space therebetween of 50 to 300 micrometers.
