Claims41
An interior assembly for transportation device, comprising:
- a glass article;
- and
- a support member supporting the glass article,
- wherein the glass article comprises:
- a glass comprising a first surface and a second surface;
- a resin film attached onto the first surface or the second surface of the glass;
- and
- an antifouling film forming an outermost surface of the interior assembly and comprising a fluorine compound,
- the glass has a composition comprising, in terms of mol %, from 50 to 74% of SiO2, from 1 to 10% of Al2O3, from 6 to 14% of Na2O, from 3 to 11% of K2O, from 0 to 5.0% of Li2O, from 2 to 15% of MgO, from 0 to 6% of CaO, and from 0 to 5% of ZrO2, such that a sum of contents of SiO2 and Al2O3 is 75% or less, a sum of contents of Na2O and K2O is from 12 to 25%, and a sum of contents of MgO and CaO is from 7 to 15%,
- the first surface or the second surface of the glass has a roughness having an antiglare property,
- the glass has a haze value of 40% or less,
- the glass has a bent part comprising at least one site having a Gaussian curvature of −0.1 or less,
- the antifouling film is formed such that the outermost surface of the interior assembly has a coefficient of static friction of 1.0 or less, where the coefficient of static friction is measured by placing a pseudo-finger contactor on the outermost surface of the interior assembly and moving the pseudo-finger contactor at a rate of 10 mm/second in a state of applying a load of 30 g, and
- the interior assembly is selected from the group consisting of an instrument panel, a head-up display, a dashboard, a center console, and a shift knob.
