Ranbar Blue DP5060 Light Sensitive Dye
Ranbar Blue DP5060 is a light sensitive dye that changes from colorless to blue. This dye is soluble in solvents such as toluene and dichloromethane. When the solution is exposed to ultraviolet light, its color changes to blue, and it returns to a colorless state when the ultraviolet light is removed. This change is repeatedly reversible.
| Temperature resistance | 220℃ |
| Melting point | 260°C ~ 262°C |
| DSC Differential Scanning Calorimetry | 270°C |
| UV absorbance (λmax) | 390nm |
| Chemical Structure | Spirooxazines |
| Appearance | DP5060 is a light green powder under normal conditions, soluble in toluene, and turns into a blue solution under ultraviolet light. |
Dissolved: toluene, dichloromethane
Slightly soluble: acetone, butanone, ethyl acetate
Insolubles: alcohol, IPA isopropanol, DMF dimethylformamide
It should be noted that Light sensitive dye itself will not change color when it is exposed to light, and it needs to be dissolved in other suitable carriers to achieve the photochromic effect. It can be completely dissolved in the carrier and presents a highly transparent state, which can realize the effect of complete transparency of the product system.
- Soluble in organic solvents, there may be slight variations in color tones in solvents of different polarities.
- Ranbar photosensitive dyes are suitable for oil-water resin systems.
- The suitable pH range for selected substrates is 7-9.
- Recommended usage in ink and coatings is 0.02% to 0.1% (w/w).
- Suitable for screen printing, gravure printing, and flexographic printing inks.
- Suggested printing background is white or light-colored series.
- Can be mixed and used with other organic pigments or dyes.
- When in use, appropriate resins or substrates should be selected.
- Suitable for a variety of resins including PP, PE, PVC, PU, PS, ABS, TPR, EVA, Nylon, PMMA, etc.
- Recommended dosage in plastics is 0.01% to 0.1% w/w.
- Photosensitive dyes can be used in conjunction with other pigments or organic dyes.
- Avoid using photosensitive dyes at temperatures above 250°C.
- Adding appropriate light stabilizers and antioxidants can enhance the heat resistance and UV resistance of photosensitive dyes.
