摘要:
The present invention provides inexpensively an article with a hard coat excellent in anti-staining property, lubricity, scratch resistance and abrasion resistance. The present invention also provides a method for forming the hard coat. A hard coat agent composition comprising an active energy ray-curable compound is applied onto a surface of an article (1) to be hard-coat-treated, thereby forming a hard coat agent composition layer, a surface material layer is formed by film-forming with a surface material comprising a fluorine-containing polyfunctional (meth)acrylate compound on the surface of the hard coat agent composition layer, and active energy rays are irradiated onto the formed hard coat agent composition layer and surface material layer so as to cure the both layers simultaneously, thereby forming a hard coat layer (2) contacting the surface of the article (1) and an anti-staining surface layer (3) contacting the surface of the hard coat layer (2).

摘要:
An object is to stick an artificial fingerprint liquid on a test sample in a constant condition. An artificial fingerprint stamping apparatus 1 operates such that as an arm 10 lowers, the self weight of a stamp unit 3 causes an artificial fingerprint transfer member 9 at the lower end of a stamp pin 6 attached to the arm 10 via a ball bush 11 to be pressed against an artificial fingerprint liquid transfer disk D1 for a predefined period of time, and thus an artificial fingerprint liquid is transferred onto the lower end surface of the artificial fingerprint transfer member 9. Then, after the artificial fingerprint transfer member 9 is positioned above a test disc D1, the arm 10 is lowered so that the self weight of the stamp unit 3 causes the artificial fingerprint transfer member 9 to be pressed against the test disc D1 for a predefined period of time.

A method of testing an information recording medium includes a step of attaching an artificial fingerprint to an incident surface of an information recording medium, a step of reproducing a signal recorded in an attached region to which the artificial fingerprint has been attached, and a step of judging whether the information recording medium is defective or non-defective based on a signal quality of the reproduced signal. An information recording medium testing apparatus includes a fingerprint attaching unit that attaches an artificial fingerprint onto an incident surface of an information recording medium, a signal reproducing unit that reproduces a signal recorded in an attached region to which the artificial fingerprint has been attached, and a judging unit that judges whether the information recording medium is defective or non-defective based on a signal quality of the reproduced signal.

The invention provides an optical recording disk, with which the worsening of jitter can be prevented effectively even when fingerprints become adhered onto a laser light incidence surface. An optical recording disk 10 comprises a substrate 2, a recording layer 5, formed on the substrate, a light transmitting layer 7, formed on the recording layer, and a hard coat layer 8, formed on the light transmitting layer, and is characterized in that, when an operation of adhering an artificial fingerprint solution onto the optical recording disk's light incidence surface, onto which laser light is made incident, is performed and then an operation of wiping off the artificial fingerprint solution that has been adhered onto the light incidence surface is repeated five times, jitter becomes no more than 1.15 times that prior to the adhesion of the artificial fingerprint solution.

A disc-shaped recording medium manufacturing method involves the use of electron beams for easily curing a resin layer composed of a resin material that is hard to be cured by irradiation of ultraviolet rays and capable of manufacturing a disc-shaped recording medium with a high yield without affecting a recording layer even by irradiating the electron beams. The disc-shaped recording medium manufacturing method of manufacturing the disc-shaped recording medium having a layer composed mainly of resin on a recording layer provided on a disc-shaped substrate, includes the steps of irradiating the layer composed mainly of the resin with electron beams of which an acceleration voltage is equal to or higher than 20 kV and is equal to or lower than 100 kV, and curing at least the surface of the layer composed mainly of the resin.
