A blank mask including a transparent substrate, a phase shift film disposed on the transparent substrate, and a light shielding film disposed on the phase shift film. The phase shift film has XRD maximum peak at 2θ of 15° to 30° when normal mode XRD analysis is performed on an upper surface of the phase shift film. The transparent substrate has XRD maximum peak at 2θ of 15° to 30° when performing normal mode XRD analysis on a lower surface of the transparent substrate. AI1 value of the blank mask expressed by below Equation is 0.9 to 1.1. XM1 is the maximum value of the measured X-ray intensity when the normal mode XRD analysis is performed on upper surface of the phase shift film. XQ1 is the maximum value of the measured X-ray intensity when the normal mode XRD analysis is performed on the lower surface of the transparent substrate.

Blank mask and photomask using the same

The present disclosure relates to a blank mask and the like, and comprises a transparent substrate, a phase shift film disposed on the transparent substrate, and a light shielding film disposed on the phase shift film. The blank mask has a TFT1 value of 0.25 μm/100° C. or less expressed by Equation 1 below:

The method of producing a polyvinyl butyral resin of the present disclosure enable manufacture of a film of which yellow index is low and durability is enhanced, when a film for lamination is manufactured, by advancing acetalization reaction of a polyvinyl alcohol resin and a butanal in the presence of a hydroxy butyric acid.

Method for preparing polyvinyl butyral resin composition, and glass-adhesive film comprising same

A film for laminating glass includes a polyvinyl acetal, a plasticizer, inorganic particles, and a trioxane-based compound.

Film for laminating glass, method for manufacturing film for laminating glass, and vehicle comprising film for laminating glass

A film for glass lamination includes a pigment portion occupying some or a whole of the film, wherein the pigment portion includes a polyvinyl acetal resin, a pigment, a plasticizer, and a trioxane-based compound.

Film for glass lamination, laminated glass comprising same, and transportation vehicle comprising laminated glass
