Abstract
A temperature induction discoloration trademark plate belongs to the technical field of trademark plates. The utility model needs to solve the technical problem that a temperature induction discoloration trademark plate which is uneasy to be counterfeited and is made from heat-sensitive liquid crystal materials is provided. The utility model has the technical proposal for solving the technical problem that the temperature induction discoloration trademark plate comprises a negative and a heat-sensitive liquid crystal layer, wherein, a trademark is printed on the negative. The heat-sensitive liquid crystal layer is made on the negative, and the liquid crystal materials used for the heat-sensitive liquid crystal layer are the heat-sensitive liquid crystal materials. On the condition of the room temperature, the trademark on the negative presents one color, and the trademark presents another color when the trademark is touched by a finger under the higher temperature. The utility model is used for manufacturing the trademark, and the utility model has the advantages that the color of the trademark can vary due to the variation of the perception temperature and is uneasy to be counterfeited, thereby avoiding the behavior of infringement from happening.
Description
Technical field
The utility model belongs to trade mark chip technology field.
Background technology
Prior art trade mark sheet has brand mark on it, be used to protect the intellecture property of commodity, avoids the abuse of pseudo-false goods marks.Its weak point is, the antiforge function of trade mark is perfect inadequately, and the incident that trade mark is forged infringement by falseness often takes place.
Summary of the invention
Technical matters to be solved provides a kind of heat discoloration trade mark sheet with the thermosensitive liquid crystal material of difficult imitation.
The technical scheme that solves its technical matters is as follows: heat discoloration trade mark sheet comprises egative film and thermosensitive liquid crystal layer; Print trade mark on the egative film; The thermosensitive liquid crystal layer is produced on the egative film.The used liquid crystal material of thermosensitive liquid crystal layer is the thermotropic liquid crystal material.At ambient temperature, the trade mark on the egative film presents a kind of color, and when higher temperature for example contacted finger touch, trade mark presented another kind of color, and this kind trade mark is difficult for forging, thereby avoids generation tortious.
Beneficial effect: the utility model is applied to make trade mark.Beneficial effect is that its color can change because of the impression variation of temperature, is difficult for forging, and can avoid abuse.Can also use as thermal detector.
Description of drawings
Fig. 1 is a structural drawing of the present utility model.Among Fig. 1,1 is egative film, and 2 is the thermosensitive liquid crystal layer.
Embodiment
