The purpose of the present invention is to provide a transfer sheet capable of providing hard coat properties and excellent weather resistance to a resin molded article such as organic glass. The transfer sheet has, in order, a base material film for mold release, a hard coat layer, a primer layer, and an adhesive layer. The weather resistance and adhesiveness of the hard coat layer and the primer layer are improved and hard coat properties and excellent weather resistance can be provided to a resin molded article being the transfer object, as a result of: the hard coat layer being formed from a cured product of a resin composition including a curable resin; and the primer layer being formed from a binder resin including a polyurethane having a mass-average molecular weight of 40,000-100,000 and including 1-30% by mass of an acrylic component.

Transfer sheet and hard coat body using same

The present disclosure provides a hard coat film comprising: a hard coat layer and a primer layer; wherein the primer layer includes a first layer of which transmittance with respect to light having a wavelength of 380 nm is 30% or below, and a second layer of which transmittance with respect to light having a wavelength of 340 nm is 10% or below; the first layer and the second layer are layered, in no particular order, in the position of one surface of the hard coat layer; and a substrate layer is included in the position of the surface of the hard coat layer which is opposite side surface to the primer layer side surface, or in the position of the surface of the primer layer which is opposite side surface to the hard coat layer side surface.

Hard coating film and laminate

An objective of the present invention is to provide an organic glass laminate that exhibits excellent weathering resistance and abrasion resistance, and that can be used as an exterior member. This organic glass laminate comprises at least the following, in order: an organic glass base, a cured layer formed from the cured product of a resin composition, which comprises a curable resin and a UV absorber agent; and an inorganic oxide film. The glass transition temperature of the cured product which constitutes the cured layer is adjusted to 80-160&#xb0; C., and the thickness of the inorganic oxide film is set to at least 0.01 &#x3bc;m and less than 0.5 &#x3bc;m, whereby weathering resistance and abrasion resistance are significantly improved, and the organic glass laminate is made suitable for use as an exterior member.
