{"title":"KODAK T-Grain Emulsions in Color Films","authors":"J. T. Kofron, R. E. Booms","doi":"10.11454/PHOTOGRST1964.49.499","DOIUrl":"https://doi.org/10.11454/PHOTOGRST1964.49.499","url":null,"abstract":"The history of the development of KODAK T-Grain emulsions was traced over the last 10 years. Four advantages resulting from the use of T-Grain emulsions in color films were delineated: increased minus blue to blue sensitivity ratio, improved speed/granularity ratio, reduced background radiation sensitivity at equal speed/quality ratio and increased sharpness through improved emulsion optics. Kodacolor VR 1000 film, announced at Photokina in 1982, was the first color negative film with a four-digit ASA speed rating, that is, an ASA speed rating of 1000 or more. An essential part of achieving such high sensitivity was the selective use of Kodak T-Grain emulsions (Figure 1). Here we will describe some of the history of the development of this technology, the benefits we feel make T-Grain emulsions worth pursuing in building color films and finally, some reasons that explain these benefits. For brevity, this paper will cover materials, although T-Grain emulsions have many useful applications in other areas. Fig. 1 Electron micrograph of a KODAK TGrain emulsion. This work is the result of many people's efforts over several years. Before the concepts we are about to discuss could be realized, the building blocks-high-aspect-ratio tabular-grain emulsions, their precipitation, including halide control and location, and their chemical sensitization—all had to be devised. For color films there is a neverending quest for higher speeds and better picture quality at these higher speeds. In the mid-1970's a special group was formed in the Kodak Research Laboratories, the Interdivisional Investigative Team, to redefine this quest. Many chemical, film structure, amplification, and emulsion approaches were considered. One aspect of the project was to analyze the emulsion technology in color films of that vintage to determine if the desired improvements in speed and quality were possible and, if so, to indicate which approaches were the most promising. Many facets were investigated, including spectral sensitization. Paul Gilman had given a paper at the ICPS meeting in Dresden in 1974 entitled \"A Review of the Limiting Factors in the Spectral Sensitization of Silver Halide and Their Correction \", which cited three primary limitations: (1) desensitization, (2) recombination and inefficiency, and (3) poor dye adsorption.

It is shown that initial photochemical sensitivity to wavelengths of the photographic spectrum between 400 and 1,200 nm depends on the presence of donor levels introduced by chemical sensitization. Reasons for the ineffective utilization of the absorbed energy are then discussed including desensitization with increasing dye coverage, fluorescence emission from dye layers, and the formation of isolated Ag atoms which do not contribute to the growth of clusters during exposure. The efficiency of latent image formation is increased when a positively charged concentration speck which introduces an acceptor level and provides a radial focusing field for conduction electrons is formed at an early stage of exposure. The quantitative theory of the operation of the concentration speck is presented, and it is shown that the photochemical efficiency is optimized for a thin circular or hexagonal tabular grain forming a central concentration speck and having a radius equal to the drift range of electrons in the field of a unit positive charge.","PeriodicalId":149069,"journal":{"name":"Journal of The Society of Photographic Science and Technology of Japan","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1985-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126650958","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
