Abstract: A laminated glass includes a first glass plate, a second glass plate, and an interlayer interposed between the first glass plate and the second glass plate. The first glass plate includes a first main surface arranged on a side opposite to the interlayer and a second main surface in contact with the interlayer, while the second glass plate includes a third main surface in contact with the interlayer and a fourth main surface arranged on a side opposite to the interlayer. The laminated glass includes a first region located on the first main surface and a second region which is located on the fourth main surface and at least a part of which overlaps the first region in a plane view. The first region and the second region have a given glass-surface smoothness.

Abstract: A substrate having at least two treated surface layers, wherein the first layer constituting the outermost layer among the treated surface layers is a layer formed by covering with a composition containing a reactive silane compound (I) which forms a surface having a rolling angle of at most 30° to water, and the second layer constituting an underlayer in contact with the first layer is a layer formed by covering with a composition (II) containing a fluorine-containing reactive silane compound (II) which forms a surface having a contact angle of at least 100° to water.

Abstract: A substrate having at least two treated surface layers, wherein the first layer constituting the outermost layer among the treated surface layers is a layer formed by covering with a composition (I) containing a predetermined organic silicon compound, and the second layer constituting an underlayer in contact with the first layer is a layer formed by covering with a composition (II) containing a fluorine-containing reactive silane compound (II) which forms a surface having a contact angle of at least 100° to water.

Abstract: A fluorine-containing organic silicon compound of the following formula (1): 1

Abstract: Coloring method for synthetic resin articles is disclosed. The aqueous solution which colors the resin surface comprises at least one polyacid having chemical formula HO.sub.2 C(CH.sub.2).sub.n CO.sub.2 H; at least one polyhydric alcohol and water including a small quantity of the coloring dye. The article is dipped or treated with the aqueous solution heated to a temperature less than the softening temperature of the resin. The coloring is achieved within a few minutes of treatment.
