Practical Processes. With acid leveling dyes no real problems exist because the dyes show good migration, electrolyte is added from the beginning, and rather like Class A direct dyes level dyeing is achieved by prolonging the times at the boil. 

Uses Demulsifier dye-leveling agent stabilizer for natural oils and vinyl polymers organic synthesis. 

This phenomenon arises from charge-transfer reactions between the semiconductor and excited dye molecules adsorbed on its surface. If the semiconductor band gap is large compared to the dye s excitation energy, electron transfer between the dye and the electrode may involve the highest normally filled level or the excited level of the dye, but usually not both. One of the dye levels will not be electroactive because it will match some energy in the electrode s band-gap region. 

It is interesting to compare this behavior with that expected at a metal electrode. If the Fermi level lies above the highest normally filled dye level, but below the lowest excited level, no dark redox process will occur. If the dye is...

Two mechanisms are possible for dye sensitization. In one, direct electron injection from the excited dye level into the conduction band of the silver halide occurs. An extensive series of experiments varying the relative positions of the dye HOMO and LUMO levels with respect to the silver halide valence and conduction band positions has established the validity of the direct electron injection model [11], In this mechanism (Fig. 4), the dye molecular orbital levels (HOMO and...

HOSTATEX LO exhibits excellent leveling properties under atmospheric dyeing conditions. Excellent dye levels with no adverse effect on light fastness are produced. 

A nonionic dye leveling agent designed for use with wool, synthetics, and blends to give full color value and even level dyeings. 

Is a water-soluble emulsifier and detergent. It functions as an emulsifier in specialty lubricants, as a dye leveling agent in textiles, and as a major component in systems used for the acid washing of printed circuit boards. 

It functions as an antiprecipitant in cross dyeing, and as a mild stripping agent and dye leveler for acid dyes. 

Anionic disperse dye leveling agent. Low foaming HYDROLEV GA-4 combines excellent dye migration with on-tone draw for consistent, uniform dyeing. 

Acid-dye leveling agent. Promotes on-tone buildup, controls barre, and migrates dye for best levelness in rapid dye cycles. Also compatibilizes acid and cationic dyes when cross-dyeing nylon blends. Recommended for all difficult nylon applications, especially automotive and carpet dyeing.

De-aerating, wetting, and dye leveling agent for package or raw stock dyeing—anionic. 

A wide range of anionic and nonionic TRITON surfactants is available for use in the textile industry. They are useful in solving wetting problems, as dyeing assistants, as dye leveling agents, as softeners, as antistatic agents as well as emulsifiers and stabilizers. 

Wetting and emulsifying agent dispersant for lime soaps in fulling dye leveling agent for acid dyestuffs. 

Ionic Type Cationic Dye-levelling agent for acrylics. 

Other applications of alkanolamides include dry cleaning soaps, fuel oil additives, rust inhibitors, textile scouring, and dye leveling agents. 

In special cases, cationic surfactants are used as dye-leveling agents (63, 64). Cationic dyes with temperature-sensitive diffusion coefficients often yield non-uni-form shades, because of the difficulty of maintaining constant temperatures in large...
