In some examples of this application, when the bending angle of lateral wall is less in the casing base member, can directly form photosensitive glue seal transfer printing layer and coating film layer on the casing base member, in this step, first of all, form the printing ink layer that discolours in one side of casing base member, the printing ink layer that discolours has predetermined pattern, subsequently, form photosensitive glue seal transfer printing layer, coating film layer and the printing ink layer of covering the bottom in proper order in the one side that the casing base member was kept away from on the printing ink layer that discolours, obtain the casing, with the adhesive force between improvement printing ink layer and the casing base member, promote the outward appearance expressive force of casing simultaneously.
Or, at first, photosensitive glue rendition layer, the coating film layer forms in proper order in one side of casing base member, then, one side of keeping away from photosensitive glue rendition layer at the coating film layer forms printing ink layer and the printing ink layer at the bottom of covering in proper order, the printing ink layer that discolours has predetermined pattern, or, the orthographic projection of printing ink layer on the casing base member and the orthographic projection coincidence of coating film layer on the casing base member, obtain the casing, with the adhesion force between improvement printing ink layer and the coating film layer that discolours, promote the outward appearance expressive force of casing simultaneously, and improve the stereovision and the feel of sign pattern or whole casing outward appearance.
Or, firstly, forming a photosensitive glue transfer printing layer, a coating layer, a first cover bottom printing ink layer rough blank, a color-changing printing ink layer and a second cover bottom printing ink layer on one side of a shell base body in sequence, then, carrying out laser etching treatment on the first cover bottom printing ink layer rough blank, forming a hollow part in the first cover bottom printing ink layer rough blank, and exposing a part of the color-changing printing ink layer to obtain the shell. Therefore, the reliability of the color-changing ink layer is improved, the appearance expressive force of the shell is improved, and the identification pattern can have more layering and texture. One side of keeping away from photosensitive glue rendition layer to the casing base member during radium carving handles launches radium carving light, because casing base member, photosensitive glue rendition layer, coating film layer are the stratum lucidum, consequently, radium carving light energy is not absorbed to above-mentioned rete, can not cause the damage to above-mentioned rete during radium carving. The bottom ink of the first bottom ink layer rough blank can absorb laser etching light energy and is vaporized to form a hollow part, and part of the color-changing ink layer below the hollow part is exposed.
The color-changing ink layer is not particularly limited in its formation, and may be formed by screen printing or pad printing, and drying, for example. The formation methods of the photosensitive transfer layer, the coating layer, and the under-cover ink layer are not particularly limited, and may be designed according to a common formation method.
The specific parameters of the laser etching process are not particularly limited, as long as a hollow portion can be formed in the first bottom-covering ink layer rough blank, and the lower part of the color-changing ink layer is exposed.
In other examples of this application, when the bending angle of lateral wall is great among the casing base member, can be attached decorative film on the casing base member, decorative film is including the decorative film base member, photosensitive glue transfer printing layer and the coating film layer that stack gradually the setting, makes the casing realize the outward appearance effect. In the step, firstly, the decoration membrane is provided, then, a first cover bottom ink layer rough blank, a color-changing ink layer and a second cover bottom ink layer are sequentially formed on one side, provided with a coating layer, of the decoration membrane, then, laser etching treatment is carried out on the first cover bottom ink layer rough blank, a hollow part is formed in the first cover bottom ink layer rough blank, part of the color-changing ink layer is exposed, and the decoration membrane is attached to a shell base body to obtain the shell.
Or, firstly, attaching the decorative film provided with the first bottom-covering printing ink layer rough blank to a shell substrate, then, carrying out laser etching treatment on the first bottom-covering printing ink layer rough blank, forming a hollow-out part in the first bottom-covering printing ink layer rough blank, and exposing a part of the color-changing printing ink layer to obtain the shell. Therefore, the reliability of the color-changing ink layer is improved, the appearance expressive force of the shell is improved, and the identification pattern can have more layering and texture.
