Articles with textured surfaces and methods of making same

Abstract

An article includes a substrate; a first layer disposed on the first major surface of the substrate, wherein the first layer has an adherence to the substrate of greater than or equal to 4B according to a cross hatch adhesion test set forth in ASTM D3359-17; and at least one ink layer disposed on the first layer having a surface roughness Ra greater than or equal 50 nm to provide a textured surface. Also disclosed is an article a substrate a coating disposed on the first major surface, wherein the coating has an adherence to the substrate of greater than or equal to 4B according to a cross hatch adhesion test set, a gauge hardness greater than or equal to 4H according to a pencil test, and a scratch hardness greater than or equal to 3H according to a pencil test set.

What is claimed is: 
     
         1 . An article comprising:
 a substrate comprising a first major surface and a second major surface opposite the first major surface;   a coating disposed on the first major surface, wherein the coating has an adherence to the substrate of greater than or equal to 4B according to a cross hatch adhesion test set forth in ASTM D3359-17, a gauge hardness greater than or equal to 4H according to a pencil test set forth in ASTM D3363-05(2011)e2, and a scratch hardness greater than or equal to 3H according to a pencil test set forth in ASTM D3363-05(2011)e2.   
     
     
         2 . The article of  claim 1 , wherein the coating has a thickness of at least 5 μm and a surface roughness Ra greater than or equal 50 nm to provide a textured surface. 
     
     
         3 . The article of  claim 1 , wherein a powder coating is not disposed on the coating. 
     
     
         4 . The article of  claim 1 , wherein the coating is a first pattern that does not completely cover the first surface. 
     
     
         5 . The article of  claim 1 , wherein the coating is a first pattern that completely covers the first surface. 
     
     
         6 . The article of  claim 1 , wherein the silicone resin component comprises a silsesquioxane component. 
     
     
         7 . The article of  claim 1 , wherein the coating is an ink. 
     
     
         8 . The article of  claim 1 , wherein the substrate comprises one of glass, glass ceramic, and polymer material. 
     
     
         9 . A consumer electronic product, comprising:
 a housing having a front surface, a back surface and side surfaces;   electrical components provided at least partially within the housing, the electrical components including at least a controller, a memory, and a display, the display being provided at or adjacent the front surface of the housing; and   a cover substrate disposed over the display,   wherein at least one of a portion of the housing or the cover substrate comprises the article of  claim 1 .   
     
     
         10 . The consumer electronic product of  claim 9 , wherein the first major surface of the article faces a user of the consumer electronic product. 
     
     
         11 . A method comprising:
 applying a coating to a first surface of a substrate such that the coating has an adherence to the substrate of greater than or equal to 4B according to a cross hatch adhesion test set forth in ASTM D3359-17,   wherein the coating has a gauge hardness greater than or equal to 4H according to a pencil test set forth in ASTM D3363-05(2011)e2 and a scratch hardness greater than or equal to 3H according to a pencil test set forth in ASTM D3363-05(2011)e2.   
     
     
         12 . The method of  claim 11 , wherein the coating has a thickness of at least 5 μm and a surface roughness Ra greater than or equal 50 nm to provide a textured surface.
