Claims13
A feeding bottle comprising a refillable hollow bottle body, which forms a bottle base and comprises an outer thread over a bottle neck for screwing on or fitting a teat, the feeding bottle containing a dye change indicator for a temperature greater than 20 degrees Celsius, the dye change indicator consisting of an imprint integrated in a bottle surface, characterized in that the dye change indicator is obtained from a composition comprising:
- i.) 10-30 wt. % oligomers selected from the group consisting of acrylates and methacrylates of polyurethane, polyester, epoxy, and polyether,
- ii.) 20-40 wt. % monomers selected from the group consisting of monofunctional, difunctional, trifunctional, tetrafunctional, and hexafunctional acrylates or methacrylates,
- iii.) 1-10 wt. % photoinitiators,
- iv.) 15-35 wt. % one or more thermochromic pigments, wherein the thermochromic pigments include an organic thermochromic dye and optionally one or more thermochromic dyes selected from the group consisting of a combination of a leuco dye, a reversible proton donor, and a phase-change material;
- a dye or a metal complex;
- and a combination of a plurality of dyes having different temperature behaviors,
- the imprint made of the composition being obtained by means of a screen-printing process,
- wherein the organic thermochromic dye is 9,9′-bixanthylidene or 10,′10-bian-thronylidene.
