| 发明名称 | Photo-curable transfer sheet, process for the preparation of optical information recording medium using the sheet, and optical information recording medium | ||
| 摘要 | A photo-curable transfer sheet having a photo-curable transfer layer comprising a photo-curable composition, the photo-curable composition being deformable by application of pressure and containing a reactive polymer having a photopolymerizable functional group, wherein the photo-curable transfer layer shows linearity in relationship between strain [γ] (%) and time [t] (second) measured by a creep test using a dynamic viscoelasticity measuring apparatus under the conditions of an ordinary temperature, stress of 50 Pa and a time period of 120 seconds, and satisfies a following formula: log γ=a+b·log t, in which “a” is a real number, and “b” is in the range of 0.10 to 0.53; and a process for the preparation of an optical information recording medium using the sheet and an optical information recording medium. | ||

| 主权项 | 1. A photo-curable transfer sheet having a photo-curable transfer layer comprising a photo-curable composition, the photo-curable composition being deformable by application of pressure and containing a reactive polymer having a photopolymerizable functional group, wherein the photo-curable transfer layer shows linearity in relationship between strain [γ] (%) and time [t] (second) determined by a creep test using a dynamic viscoelasticity measuring apparatus under the conditions of an ordinary temperature, stress of 50 Pa and a time period of 120 seconds, and satisfies a following formula: log γ=a+b·log t in which “a” is a real number, and “b” is in the range of 0.10 to 0.53. | ||
