1940s
Beginnings
Dr. R. K. Dhote, a doctor & freedom fighter, decides to attempt Indian pharmaceutical self-reliance and establishes Alta to tackle hitherto dominance of pharmaceutical production by foreign companies.
From its modest beginnings, the company grew into a recognised name in Phthalocyanine Blues, Greens, Quinacridones, and other specialty pigments, supplying leading customers worldwide in coatings, plastics, inks, and allied applications.
Building on this strong foundation, Lona has entered a new chapter where we are combining decades of experience with modern systems, disciplined operations, and a renewed customer focus. With an emphasis on quality, governance, and sustainable practices, we are strengthening our capabilities to meet the evolving needs of global partners.
Today, Lona is proud to stand at the intersection of heritage and forward momentum. Guided by Dr. Dhote’s principles of excellence and reliability, we are committed to delivering consistent products, transparent processes, and lasting value. Ensuring that the trust placed in us continues to grow for years to come.
Founder of the Alta Group (Feb 6th 1917 – July 7th 1978)
Dr. R. K. Dhote, a doctor & freedom fighter, decides to attempt Indian pharmaceutical self-reliance and establishes Alta to tackle hitherto dominance of pharmaceutical production by foreign companies.
Alta Laboratories, the first in India to indigenously develop Salicylic Acid & Aspirin, commences operations at the Khopoli plant, manufacturing patent drugs and striking a collaboration with Monsanto Chemicals.
Dr. Dhote establishes Lona Industries to diversify into pigments and dyes, and support Alta during the price control regime with a significant expansion in capacities for the Alta Group companies.
The new Ladivali factory marked a step change in capacity. Lona scaled up Copper Phthalocyanine pigment production to meet rising demand in India and abroad.
Lona became a recognised exporter, building a reputation for consistent quality pigments and customers across multiple continents.
The Dainichiseika Group of Japan (DNS) acquired a stake in Lona, bringing technical collaboration and strengthening our capabilities for global markets.
With our re-integration into the Alta Group, Lona gains new synergies in technology, governance, and scale. This positions us to contribute to India’s growing self-reliance while capturing the vast consumer market opportunities emerging over the next decades. At the same time, we remain committed to our established international partnerships, combining heritage with modern systems, sustainability, and transparent governance to drive lasting growth.
